I switched from Vim to NeoVim this year, after about 15 years on Vim.

Not withstanding this incident, I would say that on the whole it has been a good experience with Neovim. (I didn’t actually ever use the persistent undo functionality in vim. Guess because of VCS it’s less needed for my use-case).

Same timeline for me, but this was my 3rd or 4th attempt at switching. Not sure if something materially improved or maybe LLMs finally just got good enough at helping me convert.
