Which is better for UI development. Are there any differences between the two UI toolkits?
See comparison of features: http://wiki.freaks-unidos.net/javascript-libraries
jQuery is very popular and well integrated in many frameworks, while the only framework in which scriptaculous is integrated is Ruby on Rails.
JQuery will be supported in Visual Studio 2010 making it a good choice for .NET developers.
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.
I just migrated all my client side scripting from Prototype / Scriptaculous to jQuery. The result is better performance (less coding + smaller footprint) and the application as a whole seems much richer. There is something really satisfying about jQuery development.
Prototype is a great library, but I got a little frustrated that, as DNS pointed out, the developers & community seem to have gone to sleep.
jQuery is better,
it has noConflict method that allows you to easy migrate, having both prototype/scriptaculous and jquery library included
jQuery is light weight especially in compare with scriptaculous
jQuery produce very simple code that easy to test/review
jQuery support CSS 2/3 selectors even browser doesn't
For ROR there is a plugin jRails

hmmm I find that scriptaculous is easier to use then JQ because it looks more like javascript and it has more core effects...I like that about it however yes it is a bit buggy and the comunity has started to move to JQuery...However I realy don't like JQ because it is like learning a new lanuage from scratch...it looks nothing like javascript
I've been using jQuery whenever I can. When using scriptaculous, I've found it hard to find suitable plugins that just work. Most of them have bugs or lack good documentation. For example, I went through 3 slideshows including writing my own in Scriptaculous before settling in and modifying one to suit my needs. With jQuery, I just had to go through 1 slideshow plugin because there are so many of them that one was bound to suit my needs.
