I can't recommend Magit enough to anyone. Whenever I try people see me as crazy when I tell them what I do with git with a breeze. Things like committing are of course easier and such. But all the other things. Oh man. Magit have entirely changed my understanding of git.

Does anybody have a comment on the similar vimagit?

(I assume you're talking about this one: https://github.com/jreybert/vimagit)

Yeah it's probably the best way to interactively stage only changes you want to commit (`add --patch`)
