While I'm not a huge fan of circle hooks, as long as the fish gets the bait and the hook in it's mouth, it will work. Not the hybrid hooks like discussed above, but a true circle non-offset hook with a straight eye, snelled and line passed through the eye. Where they don't work well is with very small fish, where the wire gauge prevents it from setting properly. The bigger the fish and the stronger, faster runoff, the better they work. The really hard part is to just reel and add pressure quickly but smoothly when the fish doesn't, specially for bass guys, most can't seem to help themselves and have to heave back.
