I'm not really sure these two are different. How is dart2js "worse" than the Dart VM, except for speed? And even in speed, dart2js is faster than hand-written JS in many cases (see https://www.dartlang.org/performance/)

With source maps Dart is debuggable from JS AFAIK. And dart.js allows deploying Dart content in a way that works seamlessly whether or not the Dart VM is present. I'm really not seeing the difference here.
