The overreliance of the Brainbusters on suplexes, slams, etc. is going to kill them in this match. Arn Anderson is the power of the team, and he's not going to last long at the pace he'd have to cut against just one of the monsters, lt alone both of them. Tully won't fare much better.
I like the Brainbusters, but everything they do well, BB&D does AS WELL or BETTER.
Power. Arn does it well, but he's the 3rd strongest man in the ring, behind Vader and Bam Bam, and ahead of Tully. Power goes to BB&D.
Agility. Again, BB&D. So The Brainbusters' finisher was a top rope move. With their suplex / splash be any match against TWO 400+ pound men who both do moonsaults, splashes, headbutts, etc?
Technical. It's a tie. Bigelow and Vader were trained in Japan, and Bigelow was a 2-time NJ State Wrestling Champion when he lived in Neptune, NJ.
Heel Tendencies. Arn and Tully were evil heels. SO were Bam Bam and Vader. Push.
Folks, the choice is simple. You can't pull the "Horsemen" argument, because Arn and Tully alone did not comprise the stable. Vader and Bigelow owned Japanese Tag Team Wrestling, and would have been the most dominant tag team in WWE or WCW had they crossed paths for more than a few weeks.
