This might sound stupid, but I like IDEs that look good. Honestly, they all have pretty much the same feature set. I like to use applications that are pleasing to stare at for hours on end (and don't require much customization to get there).

I find most IDEs hideous and difficult to look at with so many buttons that I don't use and don't want to use.

What have you found that looks good? Sublime is ok, so is Lighttable.

I like Ninja IDE for Python. Don't have a nice looking one for Java. NetBeans is a bit less visually offensive than Eclipse.
