I sold my (regular) Party to a friend, still have my (regular) Chubby, and a new Competitor.
LOVE BWS. With the regular Chubby (can't speak to the G2), the only issue is that it can really get HOT fast and run away on ya. The added space of the G2 should diminish that. I'm not saying it's a problem -- just gotta realize that when a smaller (insulated) box starts getting hot, you gotta pay attention and choke back the firebox O2 at the right time -- or will shoot up to 4-500 faster than you think. Just need to keep a small fire and pay attention.
With the Party and the Competitor (and probably with a G2 Chubby), you don't have to be as "eagle-eyed" making adjustments.
With any Backwoods, if you dial it in (close one side completely, and close the other to a thumb width -- rough guideline) about 50 degrees before target, they'll hold real nice for ya. Of course, the model, size, water/no-water, etc. will affect that, but --- what I'm saying is that you don't really need a Guru or such.
Gotta learn 'em (like any smoker) but you won't go wrong with a BWS.
I'd love to have a G2 Chubby ;-)
