If I was going for ease of use I think I would go charcoal. The new Masterbuilt looks pretty interesting. It reaches 225°F in 10 minutes or 700°F in 15 minutes and the gravity fed hopper holds 10 lbs. of lump charcoal or 16 lbs of briquettes for up to 8 hours of use. You can control the temp like a pellet grill but use charcoal.
When I had a pellet grill I tried finishing a brisket on that and my Oklahoma Joe Bronco (charcoal smoker) and everyone always agreed the bronco produced a way better brisket. Since you have an offset I assume you will continue smoking on that. The pellet grills make a good grill for burgers, chicken, etc. but they don't get hot enough to sear my steaks how I like. They can do good at the reverse part of a reverse sear on a steak though. I think charcoal taste better than pellets and the Masterbuilt would have more uses than a pellet grill. It just seems like a lot to pay when you could just use a charcoal grill.
Let me ask you this. Why are you thinking of getting a pellet grill? For grilling? For smoking and not having to babysit?
