Anything that redirects gases to the side, will reduce the effects of gasses going forward that adds to recoil. Most of the good compensators will direct most of the gases to the sides, and some up to counter muzzle rise. It is generally considered best to block gases pointed down, at it kicks up dust and gives away your location.
If you will not be shooting prone, the last is not relevant. There are many ways to tune the muzzle rise on and AR and a break is not the best. Much of recoil and muzzle rise in an AR comes from guns that are over gassed with heavy bolt carriers impacting the back of the buffer tube. An adjustable gas block and lighter bolt has far more benefits than a break that only reduces the recoil caused by forward gasses.
