I use both Javascript/JQuery and GWT, depending on the task. I'd use GWT when I want more predictability - when an app is complex enough that I'd like to be able to move bugs to compile time instead of run time (unit test or otherwise). With GWT you don't look for a bug in Chrome's Javascript console, say. A new browser comes out with weird specifics? Great. Switch on the flag for that browser and recompile, and that browser gets a unique snowflake version that works perfectly. Over time, GWT will improve the JS it compiles to, even given the same source code. It gets faster independent of the browser improvements.
