I've been using Android Studio ever since the first public alpha, and while it used to be a hot mess, they really cleaned things up since 2.0

I personally think that AS/Intellij are the best IDEs I've ever used. That includes Visual Studio Pro.

The article seems to be complaining about WYSIWYG not working well, and slow emulators. I've never found WYSIWYG to be an acceptable solution, but that's just my opinion. But to throw the whole IDE under the bus because of that is just irresponsible.

Also the emulators are blazing fast on my machine.
