We've had both Yakima and Thule going back 35 years to the original Yakima "Rocket Box." They worked fine, and each generation seemed to be better built and designed. Generally speaking one model, and one brand would fit the vehicle better than another.
However, about 20 years ago I bought my first Packasport. That one's still in use. Other that the black gel coat fading a bit, it's perfect. We bought a second one about 10 years ago. Looks new.
I think it's just in another league as far as quality, durability, looks, maybe aerodynamics. Made of fiberglass, carpet lined. All good. I also think they appear to look harder to break into....for the non-pro thief.
The rear opening, front hinge design has worked well on some of our vehicles and not that well on others. That's been our only issue.
Not cheap. Bullet proof.
At least worth a look at their website.
