Benelli has the M2, M4, and Nova designs. Elements of those have been incorporated into many other shotguns. I won't ever buy another repeater shotgun that has anything other than a rotating bolt.
I have a lot of time with M2 knock-offs, copies from the cheap to the expensive. Both of my boys own Stoeger M3000 series for 3Gun, and they shot Trap and hunted snow Geese with them. The youngest is shooting a Cole Berretta now. I have two M2 knock off's that are one off prototypes. One had a ton of rounds through it as a 3 Gun loaner and when the parts break, I replace them with Benelli parts. The Weatherby version is, IMHO, the best M2 knock-off going. Almost a direct copy, good fit, durable and half the price with a Weatherby factory behind it. I was teaching a class with one of the one off prototypes I have in December and the extractor broke. It took me a few minutes when I got home to pull out my Benelli parts drawer and replace the extractor with a Benelli one.
But, based on the OP, I assume you are asking about ARGO (used in the M4) operating system clones. The first was of course the Remington VersaMax, which I spent a lot of time on. The Competition version was, in fact, my design that Remington duplicated off of my personally modified VM. Then the V3. I love the ARGO OS, low recoil, cleaner than gas, but it takes some dedication to understand and implement the level of QC Benelli is famous for. Sadly, Remington (of old at least) did not make muster. In over 100 that I worked on, maybe 10 were up to par. I replaced a lot of hammers, cam pins, extractors, tweaked lifters and honed out barrels and pistons that were not proper from the factory. None of them have ever gone 100K (typical for an M2) without needing almost a complete rebuild that I am aware of.
I am about 500 rounds down the road on one (M4 clone) and I am getting another one later this week or next to do some heavy use and abuse and take measurements and such. I am doing this for a "famous" gun personality, so the details will be revealed by him when I am done. Suffice it to say, in my limited work so far, I have some reservations. If you don't mind paying attention to parts and have a stock of Benelli parts (cam pins, hammers, extractors, trigger groups) on hand, I'd say sure, get one and run it through the paces with magnum buck and slugs and see what happens. If you are not adept at gun malfunction diagnosis and repairs, I would proceed with caution.
