Play them both and decide for yourself. The quality of saxophones is such that either will last as long you need. Its really like choosing favorite flavors of ice cream. If at some point you want to try a different flavor it would be a bonus that one is easier to sell than the other. Of course if you want to keep it forever then resale value wont matter.
I really like Yamahas -- a lot! I know they're not glamorous, but they do everything I ask them to do. And it's the same horn every day of the week, in all weather. Really reliable and consistent, predicatable, stable horns.
