Siege Tyrant Showdown

Forgeworld recently previewed the official Iron Warriors Siege Tyrant models.  I kinda prefer mine, which are just plastic Cataphractii Terminators with Anvil Industries missile racks glued to the top.  I do kinda like the helmets on the official ones, but that's a pretty tiny detail.

Theirs...

Mine...

Thoughts?  I like that their should pads are a little bigger, but it's not that big of a difference.
