[Optimus Vader]

A few of my choices. I went more with which versions of a character I use or prefer as opposed to just MU vs. other lines.

IM2 Comic Ironman over MU Comic IM

MU Loki (from GB set) over movie versions

XMO brown suit Wolvie over any of the MU Wolvie's I own

MU Jim Lee Cyclops (the new one) just retired my XMO Comic cyclops

Cap Movie Bucky Cap over any other comic looking Cap (I also really like the movie Cap fig) -- I retired my MU Ultimate Cap for this figure. I only want a single Cap representative on my shelf, and it's this guy... easy decision.

WW Hulk is my lone Hulk representative... I do not see that changing anytime soon. I retired my regular MU Hulk for WW version.

MU Modern Thor over any movie Thor.

IM2 Comic War Machine is my only War Machine and that's probably not changing soon either.

The revision MU Punisher is my Pun of choice (over the original release and the Target version with headband).

MU Target two pack GG. The paint colors are a little nicer for me... especially the glider. Just a little more metallic or something.

I don't have either of these, but..

MU House of M Spidy is my preferred Spidy.
I prefer the 35th Anniversary Storm over the Comic two pack.
