I'm a self-considered emacs user, but I like evil-mode. But I'd also recommend sticking to just emacs when switching (I think 20-30 days of "only emacs keybindings" may be enough) to learn a little about its normal keybindings. It's important to know where you are moving, even if then you change the furniture ;)
I've never tried evil-mode, but I always thought it would confuse me when using things like helm and magit and org-mode that (sometimes) use emacs-like bindings for their controls. Do you run into any problems with this?
