Scorponok, most definently!
Apeface and Snapdragon are both pretty ferocious fighters, and even though Darkwing and Dreadwind are some of my favourites I don't think they will fare too well against them.
Overlord is cool, I had both him and scorponok as a kid, but Scorponok is easily my favourite Decepticon leader.
I root for Scorponoks group
