I pretty much refuse to upgrade from my HTC Vive with a deluxe audio strap and TPCast until a new headset with wireless capabilities comes out. Wireless VR is an absolute must for me. Ever since the DK1, I did pretty much everything in my power to get cables out of my way. I would even run cables down boom mic stands:
I even had a retractable cable installed in my ceiling at one point. I refuse to go back to tethered VR. That lack of wire makes an enormous difference IMO. It's so easy to get completely lost in the world when you have nothing holding you back. I completely lose myself in the world. I'll pull off my headset and have absolutely no idea what orientation or where I am in my room because the chaperone is just a big rectangle. It's so awesome. A few times I've gone out of VR and found myself facing the corner of two walls without really realizing it, haha.
I have a wireless kit for my Oculus Rift CV1 as well, and I could technically use the index controller with the rift by using one of my steam controller dongles, but the deluxe audio strap of the vive is more comfortable than the rift, IMO. I also have vive n chill coolers installed on my headsets, so I can turn a fan on to cool myself down during long play sessions. With the Vive, they plug right into the headset so I only need 1 battery for the TPCast at my belt. But with the rift, it doesn't have a USB slot in the headset, so I run a second USB cable tethered to the TPCast cable and need to use two batteries -- one for the TPCast, and one for the fans. I have 3 Anker batteries so it's alright, however.
But despite all that, I choose the Vive over the rift because of the superior tracking of lighthouse. Lighthouse remains undefeated IMO. I never, ever lose tracking. With my rift, I lose tracking in the edges of the room. Like, if I'm in a corner of my room like i described above, I'd lose tracking with my rift, and I have 3 cameras set up.
If Valve releases a wireless module for the index headset, I'll buy it in a heartbeat. But as is, I'm fine with the old Vive and a pair of index controllers for now.
