RAL1000 green beige high temperature resisting Polyurethane powder coating for outdoor furniture

Polyester vs. polyurethane: I have a question concerning these two chemistries. Which one is a better choice for outdoor furniture? I hear great things about polyurethane being great for outdoor applications, and yet I hear the same for polyester. I am not sure what the difference in the two would be. I thought maybe it had something to do with the gloss level. Maybe the polyurethanes need high gloss to fulfill their corrosion protection quality? Or maybe polyester has better impact and mar resistance. Anything that you could offer on this would be helpful.
