I only found Vim syntax highlighting annoyingly slow on TeX, LaTeX and Pandoc Markdown (which supports embedded TeX math formulas), so maybe the TeX syntax highlighter is the single source of slowness. (Also, there is a tex-slow section of the Vim manual, but I think there aren't sections like that for other languages...)
But moving to Emacs had many other benefits, so I'm definitely glad I did it. The LaTeX is just what made me look for other editors, being the one thing that really bothered me about Vim.
And about the remote VMs: as user jerf said, you only run one Emacs, on a local machine, and use Tramp [1] to edit remote files as if they were local. It's great!
