Read your question again. It was not phrased as "who is cooler, Necropolis on Jebus Cross?", but rather "who is worth picking on Jebus Cross against Necropolis?". These are not the same thing, think about why yourself.
Moreover, I do think that Necropolis is cooler than Castle on Jebus Cross, but I'm not very confident about it since I haven't tested it in practice; it's based on general considerations.
