I went with the Rhino Rack Pioneer platform with backbone system and really like it.
It's aluminum so you dont get the inevitable rusting of the steel tube racks and that crap leaking all over your car.
It is very similar to the front runner rack. Main difference is on the front runner, the slats run side to side while on the rhino they run the length of the car. The FR also has a lip if I'm not mistaken.
While I dont know this to be a fact, the logic of physics would dictate that results in better aerodynamics and less wind noise. But maybe I'm just bs'ing myself there.
Part of the reason I went with rhino is that it will hold 700lbs static and i think 250 while driving. That means me and several friends can climb up there with camp chairs to watch an event. I figured the lengthwise slats would be better for that.
In order to get those full load ratings, you need the backbone system. (Frontrunner has a similar but I don't think theirs looks as good or was as short/compact). In order to get the backbone system, you needed the 76in long rack. That covered too much of the sunroof for me. About 2/3. So I put an aluminum blade on a circular saw and hacked off about 8 inches so now my sunroof is wide open. Not sure if you can do that with the front runner design.
I've had my for several years but back then rhino was cheaper for the rack but the accessories were more expensive. Front runner was the opposite. Rack was more accessories were less.
I will say the rhino rack is a PITMFA to attach/detach by yourself but it's really not something you do a lot anyway.
If I'm not mistaken there is both a rhino and frontrunner for sale on the forum. Not sure of location.
