I've used msysgit on a daily basis for about six months now and have had very few problems. The biggest one is that Visual Studio locks files while updating intellisense, so anything that updates a large number of files at once while the solution is open has a decent chance of failing on at least one file. This is only really a problem when doing complicated rebases though, and even then at worst you just have to abort it and start over. I've never used a gui for git, so I can't comment on how well they work.
