Occasionally, but when it's useful, it's very useful. But generally only if most commits are buildable and roughly functional, otherwise it becomes a big pain (as does any manual process of finding what change introduced a regression).

Same. I've only done bisect debugging a few times. I'm almost always able to use more traditional debugging especially if I have a good idea about where the bug must be from behavior.

Bisects are good when the bug is reproducible, you have a "this used to work and now it doesnt" situatiuon, and the code base is too big or too unfamiliar for you to have a good intuition about where to look. You can pretty quickly get to the commit where the bug first appears, and then look at what changed in that commit.
