Hi everyone ,,

I'm planning to start doing editor web application for my final year project , now i have to decide which RIA framework to use , i have no problem to adopt any new language and i love to learn more :D , i have seen GWT but the performance i don't think is enough sufficient , also jQuery but they don't have much widgets , finally i have seen Adobe FLEX which has a great performance so guys what think about it ?
