jQuery UI vs. Scriptaculous?

Question

Which is better for UI development. Are there any differences between the two UI toolkits?

Answer 1

I currently use Prototype/Scriptaculous, but I'm looking to migrate to jQuery. My main reason is that the developers and community behind Prototype/Scriptaculous seem to have disappeared; there haven't been any new releases in a long time, and several features are still a little buggy. The jQuery & jQuery UI teams seem to be very engaged, more open (see this, for example), and have a larger and more active community.
