I've had over 300 guitars over the years and have a few that I think are perfect:
Collings OM1SSGSB - acoustic perfection for me. I've had other high end acoustics, including more expensive, but this blows me away each time I play it.
2001 Gibson 1954 goldtop reissue (with Fralins and RS wiring kit, weighs just under 8 lbs (not chambered) and plays and sounds amazing)
Recent Fender 1963 AVRI P-bass - lightweight, perfect action and sounds exactly like a P-bass should
My 1999 Gibson Historic ES-335N is a 9. Plays and sounds fantastic, was my #1 in a gigging period. If it were a bit lighter - it is 8.8 lbs - I'd give it a 10.
I had a 2001 R8 flametop that was also a 10 - great vintage looking flame top, super low action, almost like a shredder, 8.2 lbs, I gave it to my nephew earlier this year since his family couldn't really afford such a guitar and he's very passionate about guitar and loves Les Pauls.
