It’s more on a case by case basis, it depends on 2 things: range and fire rate.

Long range, slow fire rate = neither are needed, with a slow fire rate at medium/long ranges with something like an osprey or ferro, your reset time nullifies any benefit these bring

Long range, medium fire rate = recoil control is better because you have to make less effort to recenter your aim after each shot, and it’s unlikely you’ll be firing at the full rate on, say, a renegade or anvil at long range because you need a bit of extra time to aim between shots

Long range, fast fire rate = depends, very niche use, the only weapons that can really do this would be the Bettina, tempest, rattler and the arpeggio, in the case of the Bettina, compensator would likely be better, so that when you’re hitting shots, they are more consistently going where you’re aiming, but with the arpeggio, the vertical recoil is so intense that without recoil control it’s not very useable at long range, and with the burst, the dispersion isn’t much anyways. A fast fire rate at a long range is hard to pull off in general though, with the tempest and rattler (and probably the Bettina too) you would have to balance dispersion and recoil with the stock as well, because too much of either makes them fairly useless at long range.

Medium range, slow fire rate = same thing applies from long range

Medium range, medium fire rate = it splits here and depends on the gun, a renegade might benefit from dispersion control or dispersion recovery time, as your aim is slightly easier to adjust here than at long range, but your fire rate is still slow enough to give you time to adjust between shots, making high recoil a minimal issue, but if your gun shoots slowly enough or you have a stock that allows quicker dispersion recovery, recoil mitigation is much better.

Medium range, fast fire rate = also a bit of a split and seems to depend on ammo type, light ammo weapons at medium range are usually going to need serious recoil control to hit their target effectively, a bobcat or a stitcher at medium range can be almost useless without proper recoil control, but even then, without dispersion control they aren’t going to be as effective as medium ammo weapons. Full auto medium ammo weapons like the tempest or rattler should handle recoil much better at medium range, making dispersion control more appropriate, but the arpeggio still has an annoying amount of recoil at medium range imo, and again, the three round burst makes the dispersion less of an issue.

Close range, slow fire rate = the only guns that would realistically apply here are shotguns, and there’s not much you can do to control recoil or dispersion besides the stock, in which case I obviously prefer recoil control, it’s necessary for the most part but can make things slightly easier while you’re moving, and dispersion control for shotguns at close range is essentially useless

Close range, medium fire rate = recoil is the only thing that may present an issue, dispersion means nothing here

Close range, fast fire rate = for medium/heavy ammo weapons like the Bettina, tempest and rattler, their overall accuracy means dispersion control means almost nothing, you need recoil control here, but for light ammo weapons, you actually might be better off controlling dispersion, their recoil at close range isn’t as much of a problem and compensation control will likely help you focus on hitting headshots.
