I'd say even small room scale benefits from the Vive tracking. My VR space at home (aka living room) is just barely 2x2m, but setting up the Rift in there was an exercise in frustration and a mess of USB cables.

I first tried the experimental 2 camera 360 tracking which sort of worked but had plenty of dead zones. The official line on that is to add a third sensor, which I did. It came with a 5m USB extension cable which wasn't long enough to reach the back of the room so I had to hunt around for a 10m extension instead; that in itself is a gamble as everyone's mileage seems to vary as to what will work for them.

After setting up all the cameras I still had to ignore lots of "low quality tracking" errors reported by the setup - apparently that's because my motherboard couldn't provide enough juice for all the cameras and the headset.

The lighthouses in comparison are just great. I just screwed them into the wall, plugged them in to an outlet and that was it.

I do prefer the touch controllers. The capacitive buttons are superb and well used in many Rift games. The headset itself is more comfortable than a vanilla Vive, although the Vive's deluxe audio strap make them equally as comfortable for me (at significant additional expense!)
