Mopar (Bakflip F1). I didn't spray liner my bed, used a Dee Zee bed mat and Weathertech tailgate cover. The Weathertech cover has a strip that goes on at the top of the tailgate and creates a lip that fits well with the rubber stripping on the bed cover. I also added stake pocket covers in the rear to completely seal the bed. It doesn't leak a drop, even when pressure washing or through the car wash.
Another thing I like about it is you still have FULL access to the bed once you flip it back and use the prop rods to hold it up. Really nice design and well made. I had the dealer install prior to purchase. It's Mopar badged and they added a white T handle to the left side pull cord for something to grab to open the first tier.
Like mentioned before, this subject is very subjective and personal needs, taste, and budget will help you make your decision. Really no wrong answer.
