I use Vim/Sublime for rote text editing and scripting languages. For most statically typed languages (C, C++, C#, Java, Objective-C and so on) I tend to use an IDE with a Vim emulator.

But honestly, visual debugging is nice and all but I don't know if the debugger is really the biggest loss of not using an IDE - for me it's more the code completion, navigation and refactoring support I'm after. You can get most of that going pretty well with Vim but it's a bit of a hassle.
