Lexus GX 550 Full Length Modular Roof Rack - Westcott Designs
Main differences I can see:
Prinsu has "6 integrated drop-in points per crossbar". Westcott doesn't have drop-in points so you have to remove 2 side bolts so you can lift up a crossbar a little bit to slide in anchor bolts.
Prinsu has a bend (like an "L" shape) on the side rails that increase rigidity. The Westcott side rails have a bit of flex....not much, but I can feel they tiniest flex now that I've installed roof rack grab handles on the side rails of my Westcott rack. That being said, I can grab one handle and haul my 225 lbs up and it's fine.
I don't know how much the Prinsu weighs but it looks heavier. Heavier is not better, unless lighter = cheap and flimsy, which the Westcott is not.
They both look great. Heck, they look the same and you probably couldn't tell them apart from 10 feet.
I can also tell you from personal experience that the Westcott does not make any discernable wind noise.
