Does anyone know if Eclipse's Android Gradle support is up to snuff or is it crazy not to go onto Android Studio? Is Eclipse Android totally Jurrasic Park at this point?
As android studio is now the official IDE for android programming, and eclipse IDE is no longer officially supported, yes you should switch to android studio.
I wouldn't go as far as to call you crazy if you didn't, though. You can keep using eclipse if you prefer that IDE, but you'll miss out on future awesomeness.
From http://developer.android.com/sdk/index.html:
If you have been using Eclipse with ADT, be aware that Android Studio is now the official IDE for Android, so you should migrate to Android Studio to receive all the latest IDE updates
