I yhad a GMG DB for several years and my wife wanted a BGE and we ended up with the XL. It was way too big for the two of us so Isold it and we got a medium BGE. I used a Rocks Stoker for temp control at lower heats/ It cooked wondefully and using Cowboy lump gave it a nice flavor. Pizza, steaks, pies, brissket, ribs, etc. were excellent. Most of the time I still usewd the GMG for low and slow. The BGE was too much work to light, clean, preheat, etc. I sold that BGE after building a UDS and adding a fan for the Stolker. I worked as well as the BGE for everything except high heat cooks. For burgers and brats I used my little Weber Q gasser od Lodge cast iron Sportsman grill.
My wife had cooked our brat lunch at the Royal a few times and used a Memphis Pro. When she retired a few years ago that was what she wanted for a retirement gift and we purchased one. It is hands down better than the BGE and does eveerything from jerky to steaks with no fussing or mess. Sears at high heat, cooks burgers as fast as the gasser, and does low and slow with precise temps and times. I've cooked on many brands of pellet grills and the Pro is the best for me. Well worth the cost.
