I own a Crawler. It is the bridge of a Super Strat. I agree with you the Crawler is not a modern, aggressive pickup. While it has a high DC resistance, it is definitely more of a vintage hot pickup at least in terms of voicing. I can play rock on it, but it is certainly not for heavy styles, which I am fine with.
I have played a Juggernaut in an ESP Eclipse. I am not a djent guy at all, but I was really impressed with the Juggernaut. It is lower output than the Crawler, but it is definitely more modern. The way I would describe it is it has enough power/aggressiveness to play metal (the guitar was in drop C). It is tight on the low end, but it is versatile enough to do other styles besides just metal. It sounds great clean, which you might not expect from a djent pickup. Since it wasn't my guitar or amp (it belongs to a guy I know, and I played it at his place), I can't say definitively how close it is to the Crawler (the specs on his guitar versus mine are also quite different), but I guess what I am trying to say is I like both pickups, so you might as well.
