While eclipse is my favorite, I user both IDE'S when I develop. I find Intellij to be much more powerful when it comes to development with Android and GWT. It's toolset when it comes down to it is incredible. However, I found eclipse to just be simpler when it came to managing with maven and gradle. Especially with git, I can see all my branches and such. I do however miss the code prediction and loading of other files like imgs faster from Intellij but it's a small trade-off. What do you guys use?
