I've been using a stick burner for years now and loved everything I made.  However, babysitting the fire for hours on end just became more of a hassle than it was worth.  I started looking at pellet grills, but never found one that called to me.  Oddly enough, I was watching a Kosmo's Q youtube video and noticed he was using a masterbuilt gravity series.  I looked into this and never looked back.  I love that I can set a temp and just let it be.  No more adding or removing coals and wood(maybe adding depending on how long you cook).  My first cook was a 15 lbs brisket, which turned out amazing.  I put it on the grill and only checked it after the first 3 hours.  Since then I've cooked ribs, steaks, chicken, lobster and even made some pizza.  You really can't go wrong with this grill and I've recommended it to anyone who will listen.
