There is interactive blaming, staging and committing with tig too, so give that a try.
That said though, I actually prefer using the shell to stage and commit stuff. I think I'm way faster when I'm on the shell performing those actions than in either tig or fugitive.
Tig looks great but fugitive is in my fingers (been using it for something like 7 or 8 years at this point). I'll still check it out.
Not sure when the last time you used fugitive but there was a major overhaul a couple of years ago. You can expand diffs in the commit window and stage parts of the files.
But obviously, stick with what you're comfortable with!
