I started my programming career determined to be a vim guru and do all my programming with vim.
This was misguided and after a year of wasted productivity and wasted time fiddling with plugs and dealing with broken stuff (surely by my own hand) I switched to a professional IDE and I rapidly became a much better developer.
I use vim constantly now but in it's most plain vanilla form, for the purpose of editing files when logged into Linux systems. That's all I use it for.
I really wish however that every Linux system had a clone of the old DOS edit command which was beautifully simply and straightforward and met most needs highly intuitively.
As a sidenote: can I just say that PyCharm is an incredible IDE and I can recommend it heartily to anyone. If your job is programming then it is many times over worth paying the money for the professional edition.
You can install IdeaVim in PyCharm. I've been using IdeaVim with IntelliJ for 6 years and could never go back to non-vim style editing. This plugin provides the best of both worlds.
Not to be unkind but have you tried actual Vim or adding any functionality to an ide?
Not OP but I’ve been using ideaVim for many years now and I can say that it’s quite good. It even uses my main .vimrc file and handles most of the things very well.
It IS much better than when I tried it. It parses your vimrc with and matches simple patterns to support the subset of features it does support but it doesn't really have an interpreter although one was discussed

Which means no plugins for example or complex viml. Presumably this would simply be ignored not broken.
Another approach for a different environment that seems more interesting https://github.com/lunixbochs/ActualVim I don't use sublime so I can't report on how optimal it is the idea of using an embedded vim instance is certainly interesting.
