Builders other than Breedlove might place the species in a different order. At Huss & Dalton, all top wood was thinned to the same stiffness, red spruce was used for all bracing, and most of the guitars sounded remarkably alike regardless of the type of body wood. I found on my own that thinning top wood beyond that point gave guitars a sound of more wire and less wood, a "pianistic" quality that I was after but that many guitarists didn't care for, especially for strumming and flatpicking. I'm not sure ukes ever reach that point due to low tension and nylon strings.
Wood is wood. Tonal differences come from the hands of the builder, not to mention the player. Old tradition maintained that plain wood always sounded better than figured wood, yet today most builders/players want the fanciest wood they can afford. That should tell us something.
