UltiSnips is the ultimate solution for snippets in Vim. It has tons of features and is very fast.
This assumes you are using Vundle. Adapt
for your plugin manager of choice. Put this into your .vimrc.
" Track the engine.
Bundle 'SirVer/ultisnips'
" Snippets are separated from the engine. Add this if you want them:
Bundle 'honza/vim-snippets'
" Trigger configuration. Do not use <tab> if you use https://github.com/Valloric/YouCompleteMe.
let g:UltiSnipsExpandTrigger="<tab>"
let g:UltiSnipsJumpForwardTrigger="<c-b>"
let g:UltiSnipsJumpBackwardTrigger="<c-z>"
" If you want :UltiSnipsEdit to split your window.
let g:UltiSnipsEditSplit="vertical"
UltiSnips comes with comprehensive documentation. As there are more options and tons of features I suggest you at least skim it.
From a gentle introduction to really advanced in a few minutes. The blog posts of the screencasts contain more advanced examples of the things discussed in the videos.
