I think if you're happy with the experience that the IDEs you mentioned provide you, then there is very little reason to switch.

Being familiar with vi keybindings can be useful if you ever find yourself on a minimal system with no other editors available, but the subset of knowledge you need in that situation would be much smaller than if you wanted to use Neovim as your primary development environment. I think Emacs/Vim/Neovim and the like are better suited to users who actually enjoy the process of configuring stuff like LSPs and code completions in a way that's fine-tuned to their personal preferences and works the same across all programming languages.
