I'm very comfortable with vim, so I would prefer vim solutions. I haven't got around to using emacs, and considering vim practically does everything that emacs does, I don't think I ever will.
My problem lies in the fact that I'm not particularly comfortable with latex syntax. Kile provides some sort of auto-completion of syntax words, and that is the convenience I am looking for. I can write scripts to compile the file to pdf, etc. but it's the auto-completion that I'm really after.
I've tried to get omni-complete (on vim) working with latex modules, but I have not been very successful. If you have had any success with omni-complete, please do let me know. Latex becomes very difficult if you have to look up on the web for the right keywords at every stage.
