Nemesis Prime vs. Scourge vs. Motormaster

Who do you think is the most badass truck on the road? The evil robot worthy of the "King of the Road" title? Who will win in a no holds barred, head-on collision battle? The feared tyrant or the two repaints? 
Some elaborations:
1) Scourge is RID Scourge, not the G1 Scourge.
2) Nemesis Prime refers to an evil Prime that turns into a truck, not the black mammoth, and while it's also cool to see an evil mammoth fight it out with an evil truck, let's just limit this discussion to trucks, ok?
3) Motormaster is of course, the G1 Motormaster, the tyrant, despised and feared by his teammates.
Ok, now that we've cleared it up, let the discussion begin!
And yeah, feel free to elaborate on how your favorite evil truck will dispose of the two other evil trucks.
