There's no difference in maintainability, unless you're talking about which one shows more dust/dirt (which would be the glossy). It's mostly a matter of design preference.

Thanks for the reply. We decided to go with satin finish. (Stain color will be rosewood). We will use Duraseal for both stain and finish. My question is, should we apply 3 coating of finish or 2 coatings? My contractor suggests 2 coatings. He said 3 coatings will be too thick, and easy to be scratched. Please help, we are starting on Monday. Thanks.
