My two cents…the “best” cable is the cable Oculus sells. It’s flexible, light in weight and it works. BUT…it’s 80 bucks!
I bought a “clone” (like many others have) that works just as well for 40 bucks. It’s a bit on the stiff side and a bit shorter at10 feet, but it works perfectly fine.
Oh…and make sure it has the end you want at the headset. Some are angled, some not.
