Why not Intelij IDEA?
I worked in a team (me and another guy) with Android Studio on an app. We had some ups and downs with it due to the bouncy nature of an early access preview something something but nothing really bad.
Still, I think it is adventurous and a bit irresponsible to work with an early access preview IDE in production environment so I'd recommend using Intelij IDEA for android development. It is a matured and stabled product, and it has many great advantages over eclipse that makes life much easier.
I also worked with eclipse on a commercial app and this highly praised IDE had so many bugs I can't wait for Android Studio to come out, and for now I use Intelij IDEA which saved me when eclipse filed to build the project for days.
Down goes eclipse.
