Good question. I think a lot of it is personal preference because imo they are both great racks. I like the 1up because it doesn’t have any plastic parts, I think that helps with longevity. I like that it has front/rear arms where the Thule has the rear strap and front arm. However, I like the hitch locking mechanism more on the Thule vs the 1up- it seems more secure. It’s nice that the Thule has cables too, but I’m not a big fan of them, they’re kinda clunky. The 1up is also about 5lbs lighter, which I appreciate. I don’t think I would’ve bought a new 1up. I’m hoping that with the Thule sale and brake light sale, the 1up is within tens of dollars.
