I've had folding BakFlips on two previous trucks, solid company and product. If I had to be picky, some of the panels on one of the covers seemed to get heavier over time. Possibly water retention like the foam used in spa covers. I'm currently using the oem tri-fold which was on the truck when purchased and leaning toward replacing it this year but I'm limited in choice due to having Ram Boxes. I'd also like to have a retractable allowing an option to also add a bed rack. Choices are very limited and pricey!
