I'm never fully satisfied... except maybe for my PG500, but I could find things to nit pick about that too.
Problem with PID and trying to 'grill'... Leave the lid open long, and the PID thinks the grills getting too cool and starts pouring in more pellets, causing the temperature to go up and up and up... PID needs the lid close to maintain temperature. So, grilling on a pellet grill gets tricky, since traditional grilling is with the lid open ( at least that's how I typically do it ). But then, this isn't only limited to PID type of controllers either.
Honestly, I don't know why they call pellet grills pellet grills... but that's another story. Sort of.
I do own a Stampede, and it's a fine pellet 'grill' , I even have Grillgrates now. Yes, you can sort of grill on one, and yes the grill grates help with that... but I generally don't like running a pellet grill with all the heat deflectors and such inside , while trying to grill... The drip tray gets too freaking hot, much of the heat gets trapped bellow the drip tray, this can cause discoloration of stainless steel, or peeling paint/powder coat on grills that aren't stainless. Yeah... it can work, but IMHO, it's not ideal.
Glad I got a PG500 for when I really want to grill, and fortunately I have a small family , so rarely need to grill more than a few burgers or a couple large seaks.
Things like brats and such, I've gotten to where I actually prefer these cooked at around 350F, and I can easly do this on any pellet grill, even without grill grates ( actually prefer without ).
Burgers and steaks... I'd much prefer something other than a traditional pellet grill. Maybe a Bullseye, but I've seen somewhat mixed information about how well those work.
In general I do like the Stampede. It's built pretty well, the PID easily controls temperature to within +/-5F ( but then , I don't really feel that's a necessity to cook great food on a pellet grill ). The metal is sufficiently thick, but not overly so, it feels plenty sturdy. I like the size more so than a Trailblazer, and for me personally, I don't need a grill the size of the Bull. Heat distribution is pretty good, there are a couple hotter spots near the very edges, but this is true of virtually all pellet grills. I love the WiFi... I know some people feel WiFi is a gimmick... but I tell you what, once you've actually used WiFi, you probably won't think of it as a gimmick. Find yourself forced to leave home unexpectedly right after you stuck a big hunk of meat on the grill, and you probably will see the value in being able to monitor and control the grill remotely, like I value it. ( Yeah, i can cook without WiFi, but it sure is a lot easier to do with WiFi ).
Personally I don't get it about seeing the optional gas sear station as an attraction to a pellet grill... Maybe it's because I personally don't suffer for space around my home, but if I want a gas thing to sear on , I'll buy one, regardless of what choice I make for pellet grill, and feel it's a bit silly to tie the choice of pellet grill to that particular optional feature.
