this one is tough.

I think it would be Shattered glass Rodimus in a pure face to face fight, he's unhinged to start with, would stoop to any level necessary to win the fight.

But. Movie bumblebee is extremely agile, to the point of being able to reanimate hi severed limbs and coalesce himself back together after complete dismemberment. I think he would eventually wear SG Rodimus down.
