Slimv is great. I have recently written a blog post comparing Slimv and Vlime (two SLIME-like plugins for Vim): https://susam.in/blog/lisp-in-vim-with-slimv-or-vlime/.

I posted it to Hacker News too but it did not get enough traction. The comparison table is towards the end of the post. Overall, I prefer Slimv because it supports Scheme and Clojure as well.
