I would say CRUWEAR is similar to 3V, XHP, and M4. I don't have any D2, so can't comment. Out of those 3, XHP feels the most similar to me. 3V takes a beating better than the others, but loses its fine edge first. CRUWEAR loses some toughness, but gains in edge holding. M4 is still tough, but less so and has better edge holding. Edge holding isn't everything to me though. I am pretty rough on my knives and have rolled (never chipped) S30V, VG10, ZDP-189, CTS-204P, M4, ELMAX, and probably some others I am forgetting. I have never rolled CRUWEAR, XHP, or 3V. I may have not pushed XHP too hard though. CRUWEAR is just a very well balanced knife steel that excels at nothing but lacks nothing. It holds that fine razor edge very well and touches up nicely.
