I have a 36" Blackstone, a Rectec 700 Bull pellet grill, and a standalone air fryer. Combo units "can" work okay but I've always found to get purpose built equipment over combos if you can afford it and have the space. My pellet grill is pretty much just a smoker, my Blackstone cant fry anything, my air fryer is quick and easy to cleanup... but truly I need a charcoal or gas grill for quick sear foods. The popularity of griddles these days has spurred the manufacture of many brands of griddles. I am sure they all work well.
