Depends on if you're looking to do something more modular or permanent. Both the Gobi and the Baja Racks are permanent install. If you are looking at changing it up down the line you may want to consider something more modular like a Yakima LoadWarrior or MegaWarrior or Thule Moab. Since we do get a lot of rain here WA you may want to consider a Roof Box to keep luggage and the like dry while driving around. Yakima and Thule make good versions of both as well. I went with a LoadWarrior w/ Extension on Yakima Whispbar Crossbars for a more modular. Allows me to ability add attachments for various other activities (bike racks, kayak racks, surfboards, SUP, etc.) and the adjustable bar that comes with the extension allows accommodation of any other rack on top of is so there's a little more versatility. Loadwarrior with extension dimensions are 62"L x 39"W x 6"H. It's exactly the length of the silver roof rack siderails so it matches up really nice. Megawarrior gives you some added width than LoadWarrior but with the extension the megawarrior will hang over the sun roof.
Anyway, just wanted to throw my thoughts on it since I went back and forth on this for a while and installed the Loadwarrior w/ extension yesterday. If was looking for more permanent install though I would def go Baja so I can undermount off road lights and still run 14' kayaks and 11' SUP on top. Hope that helps, I can take a pic tomorrow of mine if you like.
