I don't think there is a "best" anything, as it's so subjective, but a lot of people, me included, have a soft spot for anything in the late 80s Series 6 range.
The valve stuff (Quatra/Hexa/GP12XV etc.) from just after that era (around the time the SMX stuff came out IIRC) is also really nice, yet clearly different.
The later, Gibson era stuff, is less special IMHO.
I wonder if a better question might be "which items might give me the sound I hear in my head?"
Cheers
