I'll always recommend a large BGE, but I also have experience smoking and cooking on my dad's Traeger. And over the last couple years not a single person has complained or had a negative word to say about the result of anything I've cooked on that grill (we do a lot of family and holiday get togethers at my dad's because of his swimming pool). However, as much as I love the convenience of the pellet smoker, and it does do a great job of adding a nice smoke ring, the taste isn't on the same level as the ceramic eggs. Yes I can get the pellet smoker up and running to temp in a matter of 10-15 minutes, where the egg takes 30-40 minutes (depending on the fuel) to get to cooking temp. But when you're working on a 6-8 hour cook what's an extra 15-20 minutes of prep time if the results are going to be more enjoyable? One area I do love the pellet smoker for is a typical backyard grill with burgers and dogs (or brats). Being able to quickly get the grill up to temp and ready to cook is fantastic, but it's not going to be as versatile or offer a better tasting result than a traditional smoker or egg.
For instance, tonight we cooked pizzas on the egg at over 600ºF—something you'll never be able to do with a pellet smoker. After lighting the charcoal (I use a
looftlighter) I went inside to cook some sausage and bacon for the pizzas and rolled out the dough for my wife and kids. By the time my first kid was done building their pizza the grill was at 600º and ready to go. Pizzas took 4-5 minutes each and were amazing. However, if you're not going to cook at high temps (like pizza, or rather don't mind pizzas taking a longer time to cook sans the brick over style crust the egg produces), really hate keeping bags of charcoal around, and want the grill to be ready to go before you finish your first beer, then the pellet smoker is a fantastic product (my dad has the older
Gen 1 Pro 34). I have comfortably cooked four racks of pork ribs at the same time and the grill is big enough to accommodate a large brisket.
Traeger makes a good, solid grill, but I'd just suggest that you make sure you're okay with the trade offs of going to a pellet grill.
