I know what you mean man, I may get both version just in case TTomy screw up even worse with those stickers. Since its first image debut, I have always thought that UMagnus Prime voyager mold was marvelous. Really love that idea the hammer can also be converted and used as a gun for the bot mode. Now, UMagnus just has another signature weapon in addition to his shoulder rocker launcher. I still can't believe Hasbro remove the gray/silver paint on the abdomen and the smokestack as seen in the Cyberverse. That will certainly tone down the blue on him. Hasbro really screwed up his paint app big time.

 

my biggest problem with these two is deciding which one to get first.

 

In this case maybe getting the Hasbro version for solely the gun/hammer and repainting him nicely might be the better option... hmm...  
also the eventual UM Takaratomy Arms Micron thingy will be now bought seperatly...

 

Magnus is the second Prime figure i liked as soon as i saw, first being the Vehicon.

 

Wouldn't really cite that as a reason for him not to appear on the show.
After all, look at Knock Out, he's one of the main Decepticons of the series, and having good looking paint is actually a character trait of his! His toy wasn't quite so lucky.
