Other Frameworks similar to TLF

I'm guessing some of the people here have tried other alternatives before arriving at this solution. Can people recommend some of these other alternatives they've used before. I'm researching technologies for an in-house project, but have been having some bumps with the Adobe framework and would like to try other alternatives to see if they'd help us get the project done faster.

Would appreciate suggestions, similar frameworks or some other alternative? I'm open to all technologies.
