I have both a pellet grill and a gravity feed (Humphreys Tank II) and I personally think neither is a great option for what you are after. If I were you I'd go gravity fed for your briskets and other low and slow stuff and get yourself a 22.5 Weber kettle for chicken. While the pellet grill can "grill" it's really not where it shines IMO. A pellet smoker is for set it and forget it, low and slow BBQ. If you can afford a nice Gravity fed with a temp controller you've basically got a set it and forget it cooker with way more space in case you decide to entertain. Don't get me wrong, I love both of these cookers but, when it comes to chicken, grilled chicken, it's really hard to beat my weber set up over dual temp zones.
