The thickness of each tin, the quality of material and the colour of the tin will affect the baking. Thicker tins, with a lighter finish will result in more even baking and a lighter crust on the baked cakes. Thinner tins with a dark finish will result in less even baking and a darker firmer crust on the baked cakes.
Hope that helps.
