I think this issue, like a lot of things about Porsche cars, comes down to personal preference.

For me, I prefer the "stock" look of most cars. So I would leave the designation on. But I also understand what 69bossnine says about being a kid and seeing "turbo carrera" on the back of a 70s 911. That cursive script is a powerful image that can be "imprinted" on your brain at an early age and stay with you until you can finally afford your own car.
