Based only on the pickups? I'd suggest you tried them both to see which one fits you better and which one is better built. Besides they have different woods.
I've own a BlackJack ATX for almost a year now, and were always looking at the Hellraiser thinking "maybe I should've bought that one", but the other day I finally had the chance to try them both side by side and... I'm keeping my BlackJack. New C1 Hellraiser models are being made in Indonesia, I haven´t tried the old korean ones, but the new ones feel cheap, at least the one I had the chance to try for a day. My BlackJack looks and feels very well made.
