I have a Traeger Timberline 1300, but it's the most expensive Traeger offering :) That being said, it's huge and often needed for our larger family gatherings etc. I don't use Traeger's pellets, mostly Pit Boss and some
Camp Chef, but I love the grill itself. I've had mine for about 10 months, and it's been a very reliable workhorse for me.
The only con I'd throw out there is true of virtually every pellet grill - searing takes a bit of time after a low-and-slow, but I use
GrillGrates to help with that. And in some cases I'll throw on a cast iron skillet to get sear marks or start a reverse-sear. I also use InkBird WiFi probes to monitor pit temp as well as food temp, rather than using the single probe included with the Traeger. One is never enough, and the InkBird does a great job at a very good price.
The Timberline series, even the smaller version has a fully insulated, double-walled pit, so heat retention is fantastic and the rebound after opening the lid is quick.
Good luck with whatever you choose!!!
P.S. - I am probably going to get Blackstone Griddle as well (36") just for another way to cook :)
