I imagine the old Guilds would impress me more than the new ones. I had always wanted a Guild until I played a couple of them a year or so ago; that convinced me to go Luna.
While I was in California, I auditioned a few Guild acoustics (along with a few Takamines, Martins, and Taylors). I thought I would be impressed, but I just wasn't (the Martins didn't impress me either). I guess I'm just more a fan of Takamines than Guilds.
The 12-string version in maple in the forefront. Bought it new in '74 to drown out my Martin snob friends. It worked. Same guitar Justin Hayward uses in many of his songs (Question; especially).
