Visual Studio for me is the best one for many years - at least when it comes to .NET and C++. In Java I used to like JBuilder but they stopped supporting it so I had to switch to Eclipse. It is fine because it is very pluggable. Not the best coding experience (some say IntelliJ is much better, which I need to try) but still has quite a lot of plugins and a lot of custom IDEs are built on top of it which makes it easier to adapt to them.
