I will buy one of each and never ever use them in front of another human being. But I'll treasure them.

The only problem I see with the grimlock hoodie is that as the hoodie ages and gets washed repeatedly, those jaws are going to get mighty flappy and soon be an absolute nuisance as the top jaw sags in your face.

As a bonus, when it gets all grimy and filthy, you could dye the Grimlock hoodie yellow and start being a dragon from Atari Adventure.

Prime looks a little silly, honestly. Not that I'd make fun of a guy for wearing it, of course, us nerds gotta stick together. But holy crap that Grimlock is awesome.

I love the expression of the guy wearing the Grimlock Hooddie.

I may need to pick up the Grimlock hoodie in order to prevent child bullying.  When punk ass bullies see a badass adult like me wearing one, they might think twice about bullying child nerds.  Yeah, that's how I'll justify it.

Sure, the model could be stunned with the Grimlock hoodie's awesomeness... or he could just be embarrassed that he's dressed up as a friggin' alien robot dinosaur, which, to be fair, is perhaps not every male model's dream job.

You know, I'm glad we are living in the Golden Age of Nerds. Because in any other era any person is caught wearing these in public, they're practically begging to get bullied out of their lunch money AND volunteering to be on the receiving end of an Atomic Wedgie.
