I am surprised that somebody claim that has messed up a git repo. Since I started using git, I haven't ever messed up with my code.

I always use git on the command line. Regarding GUI tools I like to avoid them, for me is too much noise. People get lost most of the time because they don't know what the tool is doing. After all is just one more layer on top of git core tool per se (aka, what you have in command line).
