The one thing tig is really good for imo is the interactive log view with branch information etc.; it also loads asynchronously, so e.g. the Emacs repository will still take quite a while to load for all commits, but it's usable in the meantime.
Agree strongly. I find all the functionality unrelated to log exploration to be extraneous at best, and dangerous at worst, when a simple key press can actually make unexpected changes.
I'm perfectly comfortable on the command line for all the tasks except log exploration, where I find the interactive elements to be indispensable to prevent constant copying and pasting between log/diff/blame/show.
