Yakima or Thule
I own both and find both equally well built. With either you need to purchase accessories to manage the gear and Load Stoppers are a base minimum if you intend to use them for anything generic. I use the racks for camping gear as well as hauling home project lumber and such. They have never let me down. I have more extensive experience with the the Yakima system and like the round bars as gear is easy to move as it slides freely on the round bars until it is tied down.
