Well for starters, Notepad++ is only for Windows while Sublime is for Windows, Linux and MacOs X.

I guess the fact that you can customize it with Python (it has an embedded Python console) and write plugins in python makes it easier for many developers to write their own plugins, while for Notepad++ you would have to write plugins in C/C++ and use DLLs which is more cumbersome.

In any case, in my opinion nothing beats Vim (well, emacs might be close, but I prefer Vim). When I need to use an IDE like IntelliJ Idea or Eclipse I install a Vim plugin. Some time ago I was using Sublime with Vintage mode, but then I improved my Vim knowledget past basic Vim and I now I prefer Vim to any other text editor.
