Eclipse (or Android Studio) is good for when you are getting your feet wet with Android. If you don't like using it there are alternatives.

I usually use Emacs or vi. The only thing I miss when not using Eclipse with the ADT plugin is after typing say "LinearLayout ll;" with Eclipse I can type Control-Shift-O and the LinearLayout class is automatically imported in the code. I miss this, but I kind of have this in Emacs with JDE - a Control-C-V-Z has similar behavior. I could probably do some more tool work on Emacs and make it even more automatic.

I do everything with emacs, vi, ant, astyle, adb, and the Android commands "android" and "monitor". Some people do Android in IntelliJ, some in Netbeans. Some use Sublime Text.

If you think Eclipse with ADT is bad for Android development now, you should have seen Eclipse/ADT at the end of 2009. Just getting the ADT plugin to work with Eclipse was a nightmare. Having seen the improvement since then, I guess it all seems less bad to me. Although I don't use Eclipse when I do Android programming, generally.
