Both are needed. Give the spiral to us transit heads that flip out over the distortion and need a more advanced experience. Keep the geographic map for tourists, but also put a real map next to it. Many Metro stations have the simplified Metro map next to the bus map that actually has a real scale with all the streets and landmarks. Also, hotels hand out more detailed maps that include both geo scale and stylized maps. Folks that still can't read that are just completely lost.
