Diaclone/G1 Ironhide is my favourite toy of the character, personally. I guess I like it because of it's historical significance. I also like the feature where the back of the van turns into a mobile-repair-bay/turret, there's a "play set/mobile base" feel about it. MP Ironhide is great and I see what they're going for, but for me, this is the 'real' Ironhide.

If any 'Geewun' fan bashes the G1 Ironhide mold, they've just proven themselves to be noobs.
