Went with ex for Ivy and Batman personally. As a UK collector as well, I totally agree exclusives have to be worth having in general.
Had to go the whole way for that batman pf as that piece is IMO one of the best commercially available batman statues outside custom pieces of course (batman in batcave or fatboys batman on gargoyle for example) and personally I would regret not getting any form of exclusive item on it however lame...ok not a print...I wouldnt get a print
In summary I can however understand why people want the reg if not in the US.
But............... IMO Poison Ivy exclusive is definitely the
only way to go for me personally. Its of course a beautiful piece overall but the plants on the reg look just too benign for me. I think those ex plants clearly demonstrate her powers and raise the threat level of what is just a beautiful pin up statue otherwise. The exclusive statue, for me, tells more of a story which the regular edition doesn't.
