I exclusively use neovim, both on personal computers and on servers.
Just the fact that I can customize it with Lua, and therefore, languages that can compile to Lua, like fennel and guile, makes it 100 times better if you have lots of configurations. Also, the docs are better.
But in the end, vim is tge OG and I love both, but prefer neovim for my usage.
And the split isn't awkward at all. They have healthy competition and the fact that they both exist means we get better editors. Same goes for zillion linux distros out there and otger stuff.
