Cons
Con Windows-only
Con Default themes and syntax coloring not the prettiest
Some syntax highlighting colors and/or themes don't look very good - but can be customised.
Con Emacs is slow
Emacs is single threaded which means that if you enable all the great features you might be used to from Vim, it will run noticeably slower which can be quite frustrating at times. There are efforts at a concurrent Emacs, but they don't seem to be going anywhere.
