I think this piece is great. My only quibbles are the expression that is devoid of any emotion and I'd prefer the lense of the remaining eye hole in the mask to be busted out. If I really wanted this though, neither of those would be deal breakers and wouldn't make me think twice about getting it. Just like my quibble that the regular version doesn't include a smirking sculpt ("Well, here I am.") or a closed mouth, serious expression that resembled the scene when he was staring down Superman floating in the sky, didn't stop me from getting it.
Had this figure released at the same time as the other BvS figures last year, I probably would have been more tempted to get it than I am now and would have given it consideration; the main reason being the spear, which as was said, a key piece that everyone wanted which at that time wasn't available through other third parties. However, I believe I still would have gone with the regular version. As I've mentioned before, I really like the Armored suit and I would prefer to showcase it in its full form. I'm generally not attracted to BD outfits unless I'm attempting to recreate a specific scene that necessitates it.
This will make for a lot of great pictures with Superman though.
It's a vicious cycle where purchasers of either version attempt to convince themselves that THEY have the better version. Same thing happened with regular and BV CW Captain America.
Purchasers of regular version: I'm happy with the regular version. I don't really like the sculpt of the BD version.
Purchasers of BD version: That's just your way of talking yourself out of buying this version because you know this is the superior version.
While secretly, that's the purchaser of the BD version's way of also reassuring themselves that they indeed have the better version; by claiming the ones who have the regular version are all jealous of the BD version and have to talk themselves out of buying it because they secretly wish they had it.
As if both versions can't be awesome figures, but some people just simply don't see the need to have both. Pick the one you personally prefer if that's the case. Or get both if you want.
