For versatile, balls-out playing, the 330 is the nicest of the bunch...and having the longer scale of the later version of the 330 is a plus versus the earlier, shorter-scale versions (even though those earlier models have more collectable value).
Though the pickup profile is the same, they are all vastly different instruments. As I said before, I think the 330 is the most versatile...the Junior is just a sledgehammer - it sounds remarkable through the El Moto. And even with the single pickup, you actually can get some versatile tones with just a single volume and tone control.
The P-90's on the Goldtop are a bit more restrained than on the other two...and all that wood seems to smooth out the tone even more. Having said that, it is still a joy to play - gobs of sustain, the bite on the bridge pickup is a bit more restrained than on the other two (which really works nicely with the Rambler's reverb and vibrato), and to me, a significantly sweeter and rounder clean tone.
I've never really gotten a jones for having a PAF-style Gibson in the collection...obviously the prices for an even close to original PAF Les Paul (even with the recent correction in the collectable market) are ridonkulous. I bought an Epiphone Elite Les Paul (an excellent price/value guitar made by Fuji-gen Gakki in Japan), and put some Tom Holmes pickups in it for when I want that PAF-type tone and versatility.
