The compound is a bit more aggressive than the polish but still finishes down pretty well via PC. Hyper is definitely more aggressive than the compound and on hard GM paint, finished down pretty well with an LC yellow cutting pad.
I also have a bottle with a
50/50 mix of the polish and compound which does a really good job on harder paints but still finishes off as well as the polish. It does lightly haze softer paints but following with OP or 106FF takes care of it easily.
What I really like about the Optimum polishes is the lack of dust and that they are sun friendly (up to a point, obviously). I do have to work them a bit longer than
DACP or 106FF to get the same results but time saved not having to clean up the dust makes it pretty equal in time spent overall.
