No. There's no real benefit in this case. For the most part, the main practical advantage of Neovim over Vim (from a user perspective) is that there are some plugins that are only supported by Neovim and there are some types of plugins that might work better on Neovim. So if you're not using plugins this won't affect you.

There are some ideological advantages of Neovim over Vim, too, but those are relatively minor; neither is evil software, and it can be argued that Vim has some ideological advantages over Neovim, too.

For a plugin dev or vim/neovim dev, there may be other practical advantages one way or the other.
