There are so many threads about it on /r/neovim that people have started to ask just which plugins actually work together cohesively without breaking [0], something that is not asked about for VSCode. Just go through their "Needs Help" flair and you'll see lots of issues [1]. For me, I also use tens of plugins but inevitably something breaks at least once every couple of weeks.
