My friend has the Absolute Inferno and the Smokin both in box condition. The Absolute drilled a little bit stronger. To me, the Absolute picks up earlier be it the drilling or the ball's nature or surface and the backend is a nice controlled arc. The Smokin gets cleanly down the lane and has a much stronger backend reaction than the AI. Both balls are pretty strong and probably cover the same amount of boards, just differently. That's my take.
I have the Absolute not the Smokin, so I can't comment.
