I find that in actual operation Emacs is faster and that's the reason I switched from Vim to Emacs. Even after using all the tricks in Vim's :help tex-slow, Vim still lagged when I scrolled or even typed into LaTeX files (unless I turned off syntax highligh…

Not to mention that I remote into various VMs regularly which would also need to get their own server/client setup if I wanted a homogeneous working…
