As of this moment, I do not consider myself vim expert, but I know my way around it. Enough that I felt really comfortable using it. So you could say I am average Vim user. Know few commands, chording, moving around without keys etc etc. And after that I struggled with Emacs keybindings, since I finally understood philosophy under Vim. I installed Evil in Emacs and wow, I didn't expect it to be that good! And it is an option, but not for now. Not for few years, until I become just as (or even more) comfortable in Emacs than I am now in Vim. Because for few weeks I used Vim I found my self using commands from Vim mixed with commands from Emacs, to do particularly the same thing. And it would be like using some third editor. I think I cannot forget Vi keybinding that easily, it feels like it's riding the bike. So I was thinking lately, and most likely scenario is that I will stick with Emacs. It will hurt now, but it will get better over time! My guts tell me I won't regret it and that it will pay off much more than Vim. So I will basically follow the guts. And after time spent with vanila emacs I think I could jump into Evil If I steel feel the need for vim bindings and modal editing. I just think I got used to it a lot.
So I installed emacs with evil, got into a place where vi key bindings didn't work and I was stuck. So I turned off evil and stuck with normal emacs for a while. Until I knew I wouldn't be stuck if I got thrown out of vi key bindings. Then I turned evil mode back on.
No need to wait a year or more. Just Get a basic familiarity with plain emacs and then switch to evil. You get the best of both worlds.
