I think Traeger's game is sell as many grills as they can and make money on the accessories. I'm guessing that 75% of the people that buy a pellet grill pick Traeger as their first one.
I just saw an Ace Hardware commercial on TV. They will assemble and deliver for free.
Gas - Weber
Charcoal - Green Egg
Pellet - Trager
ACE has been doing that for a while.
Traeger has wormed their way into being sold by many businesses, so the name gets seen and that is what people think when they initially go to buy one.
They even had a TV Infomercial. They do a good job marketing.
I "try" to buy USA made products when I can, which is why my first grill was the Memphis Pro. Never even considered Traeger.
