Comps are totally subjective anyway, but I'm gonna give you my totally subjective conclusions from my own ownership and comparison of all of the products.
First, IMHO the 460s are a totally different mic with the actives and CK1x setup than they are with the CK61 and CK63. IMHO, I thought the 460's sounded better than either the JWMod 460 or the 480s, but ONLY when connected through the stock active cables and CK1x capsule (which are darn near impossible to find). I can't comment about the CK3x capsule because I never owned them.
If you put CK61/CK63 directly onto the bodies, I thought the both the 480s and JWMod 460's sounded fuller, with a better soundstage when connected directly to CK61s and CK63s than the 460s...pretty marked difference to my ears when I ran the comp.
I thought the JWMod 460's sounded damn near identical to 480s in every sound comparison test that I did between these two, with a nod going to the JWMod 460s for a teensy tiny boost in fullness and soundstage...although if you like presence the nod goes to the 480s...having said this I'd be hard pressed not to conclude that these two mics really don't sound identical.
My opinions...nothing scientific.
