None of that says "really bad UI". Quirky, sure. Not as straightforward as others. Could definitely be improved. But not "really bad". Though I will add that the index is a horribly named concept and it really bugs me that different commands use different names for it ("--cached", but sometimes "--index"). They need to rename it to "staging" and change all the command line options to --staging (keeping the old ones as hidden backward compatible options, of course... "diff --cached" is engrained in my memory at this point). I think that would make things more consistent and clear.
