From the G1 bunch, definetly Predaking. Devestator would be in second followed by Computron.

The favourite one that I owned was the combaticons, but out of the ones that I wanted to try would have been Defensor.

Predaking with Devestator a close second.

Well if you went by Hasbros notions, you'd think it was the Combaticons, and their various re-colors.

 

But my Fave is Defensor.

Seacons = King Poisidon

Predacons = Predaking

Technobots = Computron

Terrorcons = Abominus

Team Bullit Train = Rail Racer

Constructicons = Devestator

The Seacons formed Piranacon in the US. In any case, Devastator was okay, but my favorite has always been Abominus and the Terrorcons. You can't beat a team that has a Nose Monster (Yeah, I know it's supposed to be some kind of mole thing, but he looks like a giant walking nose) and a Land Shark, with the most articulated figure out of all G1, to boot. Plus, the combined mode looks pretty nifty, too, and looked fairly nice in the show the few times he appeared (Call of the Primitives! With antennae fwinging! Fwing!).

allright transformersjunkie!!

the bullet trains are the best combiner, (i call him railrazor, sounds cooler) because of coolness and articulation. each of the three bots is awesome and the gesalt looks and plays amazing!!

I had Devestator and Defensor as a kid, and would love to have them complete yet again. Devestator gets my vote because I loved the Constructicons so much, but Defensor was also quite cool.

Already Have RailRacer and not to mention I'm rebuilding my G1 collection I already have complete RID, Armada, and everything those far from Superlink/energon

Yes I know, but I prefer the paint job of the Japanese Seacons. The all white looks really nice. I just wish mine would get here already.
