I think you'll find that all of them are very similar in terms of ORM, Session, Cookies, etc -- they are, more or less, the same toolbox.

However, the devil is in the details. Once you start managing something sufficiently complex you start to see what details constrain you in bad ways and such. I'd guess that you don't get to that point until way after you launch.

That would be really interesting to see the details required for each framework in comparison to each other.
