If it were for looks only, the Jazzmaster.
For a guitar that I'd likely never let go, the Reverend Double Agent III. With the Reverends, there is nothing that will ever need upgrading. The build quality is amazing, and the range of tones with the Bass Contour knob is unique and useful.

The only reason I bought the Gretsch over a similar Reverend is the new blacktop pickups it came with. I'll still get another Reverend or two down the road. Their only weakness is that some models don't have the classic visual appeal. That goes out the window once you play it.
