The ASAT Classic Custom has been discontinued in favour of models with a P90 in the neck. There is a fairly big difference between an ASAT Classic and an ASAT Special. The pickups in the Special have more of everything, in a good way. If I were to choose one I'd probably go for a Classic as it is much easier to find aftermarket pickups should the stock ones not be to taste. That probably sounds like sacrilege to die hard G&L guys, but there is a reason why G&L have introduced alnico and P90 versions of the ASAT .. lots of players like to tinker or mod their guitars, and pickups are very often first on that list.
Having said that I have three ASAT Specials and I've toyed with replacing the pickups on at least one, but they are all still stock. Nothing else sounds like those big MFDs.
gratuitous pics ...
ASAT Special
ASAT Classic Custom ( newer model )
ASAT Classic Custom ( older model )
The newer ASAT Classic Custom has ( had ) a neck MFD that sounds fatter than fat, fatter than any single coil I've played. The bridge pickup is wound to match the neck pickup so it is not the same as a regular ASAT Classic bridge pickup.
The older ASAT Classic Custom pictured, late '90s, was basically the same as a current ASAT Classic but with alder body /ash top, natural binding on the top and a belly cut. I had that one modded with a Wilde L200TL in the bridge and a Fender Vintage Noiseless in the neck.
And don't forget the Bluesboy .... this one now has a Fender Vintage Noiseless in the bridge.

Why more than one ?
For the same reason there are lots of different flavours of ice cream of course
