If you're giving thought to other JS frameworks, take a second look at jQuery and its UI parts, besides how can you go wrong with a framework that was put together by the same man responsible for firebug. Actually, a better indicator was this years Ajaxian conference, one of the questions put to the ask the experts panel was what framework would you use if you weren't allowed to use your own - jQuery was the one mentioned most.
