If you want an iconic Thor, then TDW (light & heavy armor) or AOU versions are the closest to me (I'm a big Thor fan. Has always been my favorite Marvel character). I never picked up the AOU cause I got suckered into buying both TDW versions. But I prefer the TDW head sculpt over the AOU one and the bronzy colored accents over the silver from AOU, even though silver would be more comic book accurate. And the light armor TDW looks better without the blue under shirt he has on under the AOU armor. Which is more comic accurate on the TDW Thor's. I did pick up a parted out light up hammer from the AOU Thor though.
I also have the original and the Avenger's Thor. Don't like the gladiator look at all. I have him in a 6" figure. That's good enough for me.
Road Worn Thor is nice too, but prices are out of hand. Kinda sorry I missed that one but won't lose sleep over it.. I passed on this guy too, as I really don't like short haired Thor (as above with Gladiator Thor, I'm content with a 6" version).
Was so hoping the SS comic Thor would've nailed it, but the body/build is way too small. And that price of $250 was laughable.
