I have run BFG's on other cars(not a Viper) and I certainly would recommend them over Goodyear or Firestone.
I don't have enough experience or use with the Michelins so far to compare them with BFG's, but so far the Michelins seem superior to them all.
My opinion
Goodyear GS series good traction, but wear to fast.
Firestone so so traction but wear better than goodyear
BFG's Comp series great traction and excellent wear
Again my experiences were with vettes.
