Please note that I am not a carseat tech and I am not paid by any carseat company. I am not a professional and simply explored the carseat market on my own, from the perspective of a mother trying to choose from a variety of seats. I encourage all parents to explore carseats in person and with their child before settling on any seat. Why?
The best carseat is the one that you can install correctly into your car every time and the one that your child can ride in comfortably and securely every time. Brand, price, marketing, cup holders etc will not protect your child if the seat is installed incorrectly or used incorrectly.
To review the carseat safety topic, check out my carseat album:

And Jennifer Mann's safety summary:

You can also find a spreadsheet of specs here. This is probably the "gold-standard" for specs.

Meet the models:
DD (Dear Daughter) is 26 months old, 36 inches tall and weighs 29 pounds. She is currently rearfacing in a Roundabout, True Fit or XTSL. DS (Dear Son) is 3 months old, 26 inches tall and weighs 17 pounds. He is currently rearfacing in a Snugride32.
Here are the carseats, from lowest price to highest price. The specs are a quick measurement with a tape measure and no child in the seat. I am including my measurements for a general review and do not claim they are gold standard.
Cosco Scenera40
The Cosco Scenera40 is the cheapest seat on the market. It is basic and has thin padding and one cup holder. The new model now rearfaces to 40 pounds, but notice that it still only forward faces to 40 pounds, so you will be buying a second seat later down the road.

| Cosco is part of the Dorel company (includes Safety 1st, Eddie Bauer, Evenflo, Disney, etc). Many people remain wary of this company's quality, so I found this defect a bit funny. |

| Still room to rearface (RF). |
Price: $50
Weight: 40/40 (40 rearfacing/40 forwardfacing)
Shell height: 23 (determines how long a seat can be used)
Base width: 15 (important to know for cramped or small middle seats)
Widest part: 18 (helps for those who are installing multiple seats)
Lowest slot: 7 (helps to know if newborns can use or not)
Highest slot: 15 (determines how long a child can remain harnessed)
Graco Comfortsport
The comfortsport feels pretty luxurious, actually. It's padded and squishy. DD likes it and had it as one of her early seats. The primary concern is that it rearfaces to 30lbs, the lowest on the market. So unless you are getting this seat as a gift or almost free, it does not make sense financially to buy it.

Graco Myride65
This seat is a mid-range, basic choice that will probably serve the needs of most people fairly well. It has a shorter shell height than most other seats at 24.5 inches, but that is not severely short. It appears to do a great job at securing newborns and has a newborn insert. It is fairly easy to install in most vehicles. If puzzling multiple seats side by side, it can be hard to find seats that will install next to the myride. Otherwise, if you're not sure which seat to get or feel overwhelmed, this one will probably do the job just fine for you.

Price: $130

Evenflo Triumph65
I have little to say about Evenflo seats b/c I have not used them. I have heard techs complain that they can be hard to install and some of the weights/heights do not appear to make them economical choices. But other than that I have no comment.

Safety 1st Alpha Omega
This seat previously had a bad reputation, but the newer models have a higher shell and higher harness weight, making it a potential option. You can read about the changes here: http://www.mothering.com/community/forum/thread/1032699/safety-1st-3-in-1-convertible
I still don't like the seat. There's something upright and stiff about it that DD does not like and it has lower weights compared to other seats. Also, many people think this seat will be their one and only purchase, but the booster mode tested as a "worst pick" as it tends to fit the majority of children unsafely. For the price, you can find other seats that fit better and last longer, even if they don't carry the all in one claim.

Britax Roundabout
I own the Roundabout because I found last year's model on steep clearance. Britax does have a feeling of sturdiness and luxury. I initially didn't like the Roundabout and was even going to sell it, but used it as a backup one day and DD actually asked to stay in it. The Britax signature base puts the seat up higher than most other seats, so this might be a good option for kids prone to motion sickness. Another thing I noticed is that the curve of the sides supports small children. If considering Britax seats, it might be especially important to offgas the seats as they tend to have higher toxin ratings at http://www.healthystuff.org. (I recommend all seats be offgassed/outgassed.)

Safety 1st Comfort Air
The marketing on this seat really catches the attention of a lot of parents. I am not impressed. The seat is similar to the Alpha Omega frame; fairly unpadded, rigid and straight, cheapo feeling. It's narrow, so fluffy kids might be uncomfortable. And the headwings will not fit perfectly at every stage. They seem to work best for older toddlers. The tall shell and harness height, so those with tall/skinny kids liked it, but the company came out recently, clarifying that there are absolute height and angle restrictions:

Britax Marathon Classic
Ah, the seat that arguably was the first to drive change in our market of convertible seats. Britax is a renowned carseat company that most parents highly regard. As I mentioned under the Roundabout, these seats are certainly luxurious and feel well-built. But the features once considered special are now standard. That being said, the Classic Marathon's price has dropped from $279 to $159 and it is now steel-reinforced. Are these options enough to keep it on your list? It's certainly worth considering.

Learning Curve True Fit
I own this seat and like it. It is a low, wide and tall seat that will fit bigger/taller kids. At least by my measurements, the shell measured taller than the XTSL. I also like how accesible the installation paths are (you can pull the fabric back to see what you are doing). That being said, it has an infinite harness and for many kids (especially petite or small kids) you have to tighten and buckle the harness in a certain pattern. This IMO increases the risk of not using the seat correctly. I listened to a lot of advice and tried a lot of things and was NEVER able to harness my toddler correctly. I gave the seat to her older uncle to use forward facing as he had no problems with it. With the lower rearfacing weight (35lbs), tallest shell that might not fit in small cars and the harness quirks, this seat might not work for a lot of people.

Sunshine Kids Radian XTSL
This seat is not the BEST, nor is it even the EASIEST install for most vehicles. It is, however, the only seat that rearfaces to 45lbs on the American market. And it is the slimmest seat, which allows parents to install more than one seat (and get 3 across in most vehicles). It does not rearface correctly in many smaller vehicles and the latch might be incompatible with some vehicles. Search http://www.car-seat.org to see if your car is compatible.
