I think it all depends on what you are looking for.
I had a Coleman NexTrip deluxe grill which was REALLY versatile but gave it away this spring because I had bought some induction cookers for pot cooking which pretty much relegated the Coleman to grilling or a griddle. For grilling it cooked pretty hot but did a good job. I just purchased a Blackstone griddle for cooking things in that manner and will get the Q2200 when I get to a store that has one strictly for grilling. I like the larger dome and 12k burner vs the 2 10ks in the Coleman....and that is why I bought it
The Coleman connected directly to the RV with an adapter hose if/when I wanted to.
There are many out there. So many options, but, they all really depend on what you like to do and how you like to do it. There is one by Smoke Hollow that has a wood chip tray to impart a smoky flavor if that is what you like. I passed on the Q last go round and bought the Coleman for heat and versatility; now, I'm back at getting the Q and buying a bunch of "stuff" just so I can cook "more stuff"
