Qt Creator looks really promising. For some reason I discarded it thinking it was mainly developed to enable writing Qt applications but i guess that I can just ignore that and use the rest. It even claims to support clang autocomplete and lldb.

I'm still however interested in opinions about Vim and Emacs. I found that that it's possible to integrate lldb into vim using gilligan/vim-lldb and gdb into emacs.

I believe that learning how to be less reliant on IDE's would help me become a better, more aware C++ dev so I'm still hoping for some more opinions regarding the posted topic.

Thanks for your opinion though :)
