Forget the cookies and pastries, we use this sheet several nights a week for baking fish, primarily salmon and tilapia.  The fish lifts right off the pan.  (Salmon has oil and we brush our tilapia with pesto, so I dont know how the fish comes off if you do not use oil or if the fish does not contain any).  I love that this pan is dishwasher safe when so many out there are not. PS. I did bake some cookies for the holidays and they do lift right of the sheet.
