I love Notepad++, but when I started using Sublime Text 2, I purchased it, and never looked back.
The more I use it the more I like it. Sometimes I have files that still open in N++ and I quickly switch out of it into sublime. Oh, did I mention at the command line (in OSX) you can open files using the subl command (Very awesome).
My other nitpicks with N++ are the lack of a "yes to all" on the change-detection dialog when you do a hg update, and the way gedit seems to do ctags so much nicer. Seems like low-hanging fruit, maybe i should try to get a patch in..
Still, hard to beat and easy to recommend. I use it every day (it bought me a car!).
The Zeus editor has ctags support that is effectively automatic..
All the user has to do is create a project/workspace and add files to that workspace.
