To each their own. I quit using syntax highlighting about 10 years ago and won't ever go back (been programming for 25 years, vim/neovim user for 24 years). I just like it better, it works for me. It definitely does not make things "difficult for the sake of it" (for me). There are dozens of us! :)
(As to the rest: I use a pretty minimal set of plugins and I use the built in nvim C-o/C-p or C-x C-o/p "dumb" autocomplete. At least I think it's built in...)
