tig is great -- it makes it very easy to stage individual lines of code (using 1) or to reset unstaged changes on a file (using ! in the status view).

it covers like 80% of my use-cases (which I use 99% of the time), and weirdly magit gets me the other 20% if I can remember which trail of breadcrumbs I follow through helm to make it happen. For the easier stuff I just drop down into the cli though.
