Different goals I think. Dart is supposed to be a "Better JavaScript" (except not JS...). If Dart were to take off and all browsers implement it then GWT could probably even compile down to Dart instead of JS.

Dart compiles down to JS right now as an in-between "please don't hate our language because no browser implements it" step. The focus for the future obviously is that they drop the compile step for Dart and run it native in the browser.
