I'm satisfied with the Roks on my 2015. They're made of a harder plastic material (very rigid) compared to the Rally Armor, so you'll need to work them into shape before you install. The only concern I had with them is that 1) they rub against the inner section of the fender, so I put some clear 3M paint protector in that area to stop it from rubbing the paint off, 2) for the front flaps, they create a "pocket" area between the wheel-liner and the flap where rocks, stones, mud, etc. can collect.
Heard good things about the Rally Armor too if you can swing the added cost.
