I've used Prototype and Jquery fairly extensively. I absolutely loved the DOM navigation features of Prototype, they were shamefully easy to use. Jquery can do it too, but it isn't as simple. Jquery works better with groups of elements rather than individual elements. In many cases, the code looks cleaner. There is also much more support behind Jquery... one of the reasons I switched from Prototype was because support for IE8 hadn't arrived, and it didn't support chrome properly -- checking the Prototype site right now, it seems the stable version still doesn't. My vote also goes to Jquery.
