Never attempted to make the move (friction, sizeable vimrc). I've mostly been using the distro builds, which for neovim often meant an outdated version.
I can also admit that I've benefited from the project, even if I've never used it. Like everyone using Firefox is currently benefiting from WebRender, despite never moving to Servo.
We often find criticisms of forks in OSS (waste of resource, we should work together through a common goal), but the truth is that this flawed mechanism allows for innovation and experimentation. Which is also why the BigCos that ship different competing products (say, messaging apps), are often the most innovative because it prevents (some kind of) in-fighting and cookie licking.
Agreeing with another response: I have a vimrc that I've accumulated over something like 20 years, I kept putting off switching to Neovim because I anticipated it would be a headache, and in the end it only required something like half an hour to make the switch, probably less. I would classify it as "easy peasy".
Speaking for myself; vim's always available whereas I have to faff about (especially on older systems, or where I'm not admin) to get neovim working.
The .vimrc files seem to have to live in different places meaning the scripts I've written to install vim/vim-plugins will need to be altered.
Some plugins don't work properly.
I've never got neovim working on windows (can't get the colours quite right)
I tried the built-in terminal and thought it was a great idea but struggled to seamlessly hop between panes, pipe the output into files and open in other windows or copy/paste them. Tmux solves all those problems so I never use the terminal (and if I needed to it's in vim now).
I liked the attitude of the project, but I still have no use for it. One idea which might make sense would be for the vim project to accept the neovim source; merge it back in as vim 9 so all the great refactoring, and other functionality is available for everyone and any wasted effort on two almost-identical projects is avoided.
