A shame their personalities won't at all show...

I'd rather have more military vehicles and not automobiles, so Combaticons.

 

In one side... the combaticons would even up the military vehicles,but still brawl might need to be either require a "rebuild upgrade" body wise,or replace him with someone bulky like Strika or Sparkcrusher. but in a nother we might have a team of cool vehicle modes with "turbo" stealth force modes. but the stunts might be risky,might require a good rc-control rigging and some added "nitro" for the insane stuff. like driving on walls,big-air jumps,etc.

...really it would also depend on what setting in which either where a "mayor" battle would be. like if the there is a battle scene set in las vegas or somewhere flashy involving the stunticons,riding on top of buildings blowing things up and all that good stuff,forming menasor in some badass and acrobatic way. while the comabticons well they can be great if the battle was in a jungle or a city capital of sorts,blasting thru walls,buildings,etc. and... hmmm... what else...

 

Out of the two choices, the Combaticons win easily for me

 

Do a Bay job on the Stunticons' personalities, but they shouldn't be cannon fodder for the Autobots;they should kick major ass and have a good combiner mode. Movie Devastator walked on all-fours because he was so large, there was severe strain on his component parts. Menasor's biggest component is a semi, so he sholud be able to stand up right.
