I believe that the wood species is not the primary determination of what constitutes the best guitar. I have played guitars with top quality woods that I wouldn't pay a nickel for. What determines a great guitar is the build (shape, size, bracing, wood thickness, etc.). For example, the best guitar for my purposes is the Taylor grand auditorium. As such, I own 6 Taylor grand auditoriums, each with a different combination of wood species. I consider the woods merely different flavors of a great build, with none of them being superior to the other five. Hope this helps.
