Everybody loves Optimus Prime (except Megatron of course, but he doesn't really like anyone), and of course, everyone's got their favourite version of Optimus.
I'm gonna go out on a limb and guess most of you probably like the G1 version, but I thought it might be interesting to see how many of you prefer another version.
I, for example, am kinda fond of the Unicron Trilogy version (specifically, his Cybertron version), because I really like how he can combine with other transformers, and I just generally like the look of him. I guess the Revenge of the Fallen Optimus can do this too, but I've never really liked the look of the Bayformers.
So, what's everyone else's favourite Optimus?
