I had the Bakflip F1 on my 2013 Ram with Ramboxes, and won't look at anybody else for a cover.
It is rock solid (or was as I don't own the truck anymore), and can fold up out of the way giving me full access to the bed.
My 2019 Limited came with the stupid black rail system, so now I have to pay to get the chrome ones! Grrrrr...........
I know people say it's easy to just lift the trim-fold covers off if you need access to the full bed, but what do you do when you are out somewhere and make an "on the spot" purchase.......where do you put your tonneau cover then?
I'd love to save some money and go with a different system, but considering mine did everything it was supposed to do......well it doesn't make sense to look anywhere else.
