The Green Mountain will hit 500, which was a big selling point for me. You can char a steak on it with ease.@Briar Tuck
How high does the temperature go on your green mountain? My master built tops out at 275. I love mine but being able to have a high heat for certain recipes would be nice.
In contrast, my Traeger tops out at just over 400.
Having owned both for a while now, I can say that the Green Mountain is superior in every way. Traeger has the name recognition, but Green Mountain makes a better product.
