Hey man, sure--Greg is what I go by.

The Skyline Hollowbodies are really excellent, they're my favorite Skylines. I have one with Dark Star pickups.
I do have a Lakland JO (jazz bass) with the single-coil Chisonics that I like a lot, those pickups have been out for a couple years. Agreed, they're fatter-sounding than regular J pickups--though they still have a growl. On the Hollowbody you tried, those are humbucking Chisonics, which are crazy fat to my ears. (There's also a switch on the HB to switch to single-coil mode.)
The US models don't necessarily sound better (I have 2 US Laklands and 2 Skylines), it's more about their amazing necks and all the options you can get on one, along with a few other bells and whistles. The Skylines are really sweet basses in their own right, IMO. Hope you can get one!
