G1 Ultra Magnus = most overrated toy and character ever!
Even as a kid I disliked this toy (a friend had it so I did get some hands-on experience with it) and never desired to own. Which still stands today. Its only redeeming feature was that Autobot cars could go in the trailer. But then you could do that with OP too.
My dislike for the toy was amplified by my dislike of the character, another aspect that remains to this day. I never, never liked this character at all. And tbh, I'm not 100% sure why, but he still remains one of my most disliked characters in the whole TF universe. (Maybe because as a kid I was a card carrying member of the Galavtron fan club).
I was also a little offended by "Target 2006", when the writers implied that UM is so freaking fantastic, that three triple changers are only barely enough to compensate for his absence. Pah! I'd put $5 on Springer in a toe-to-toe with UM anyday. And an extra $5 if he's got Sandstorm and Broadside with him.

Anyways, thats my humble 2cents on UM.

Note: perhaps this post should be in the Overrated thread, but hey, the UM conversation was here...
