The Britax Boulevard/Decathlon/Marathon all have a bigger seat shell, higher harness slots and harness up to 65 lbs.. Great for big babies or ones who are tall or long torsoed.
The Evenflo Titan Elite harnesses up to 50 lbs., but I believe it has the same seat shell as the 40 lb. version, which means it will not accommodate tall or long torsoed kids for long. They will outgrow the seat by height long before reaching the weight limit.
