Neither are platforms id currently considered being compatible with "alot of use".... and by "alot of use" im viewing that as in >1000rounds per year kindov use. Considering the cost of ammo that affiliates with that amount of use, it makes more sense to budget for options in the 2k plus price range.
For lighter use applications i do view the SU16F's as being a better purchase due to there notably cheaper price. An overwhelming majority of them seem to cycle very reliably. And the receiver breakage issue seemingly died off pre covid with the gradual introduction of staked op rods in gen 2 uppers. They have rudimentary controls, aint accurate, have limited customization and likely wont survive a tumble off a moving ATV. BUT they are super light, nimble, take 10rnd Stanag mags and are VERY effective at dishing out .223 in a very short amount of time.
