You can use the same argument about debuggers, dependency managers, editors, etc.

If you are happy with whatever tool you are using, why change?

Version control is social and there you can see a few maniacs ruining it for the rest of the team.

Debuggers aren't much harder than pour and drink. Dependency managers are pain in the ass (unsolved problem in CS) but you don't wrestle with them every day. I don't use very many features of my Eclipse and I don't use terribly many commands in vim. I also use arrows, I kid you not.
