pictures of my collection are up in the collection sub-forum(hopefully a massive update in a few weeks ), i lean more towards the autobots because in general i find they have cooler figures .. i have 14 different optimus primes :S but who doesn't have a million of them? :P
i think my favorite figure that i own at the moment would be war for cybertron optimus prime , favorite character from g1 would be ultra magnus ( though there has never been an ultra magnus figure that i thought much of )
