I'd have to agree with that overall...
While others are often exceptional in a few rides I've never been buzz sawed so often in so many different rides by a single person. Now in fairness there are a lot of excellent sticks I havent spent as much time around (not that I've got alot of time with BH either).
On a broader note I'd like to make a few observations. There are an awful lot of great sticks for specific rides. To pick just one is almost impossible. Further a few guys are actually better in other rides (example Bat is a better jug driver then mossie driver IMO).
Another aspect is the gunnery component vs the ACM component. Personally my ACM is much much better then my gunnery (not that my ACM is always uber..but my gunnery never is). I lose a lot of fights that I feel that I out flew the other guy but couldnt convert 5-6 shots only to get 1 timed on a split 2nd crossing shot. Thats one reason I fly the A-20 so much...what I give up in ACM potential I gain 5X in gunnery.
I used to fly the hog a lot and am a pretty decent hog driver overall but never have been truly comfortable in the 1A for some reason. I grabbed a D to lug some ords and all of a sudden was "in the zone" for 1 hop. I had 5 kills on 5 shots, all were 1 time snap shots clearing squaddies. Every plane blew up outright or lost a wing/tail...total ammo expended wasnt more then 40-50 rds total per kill. Of course next hop was the same ol me and I laid out 1200 rds or so from 400 to get an assist

What makes the guys like BH so dangerous isnt just the ACM, its the gunnery.
