Picture quality on the One Pro is amazing. Crisp and clear. Sound is really good. Image is stable, but reacts weird in moving vehicles when using the body anchor mode since it can't know about the motion of the vehicle. I wish the fov was a little wider, but it's one of the best in the industry, so I'm nitpicking. My biggest complaint is that it gets a little warm, and has to rest on your forehead for the best view. But it's effectively replaced my TV in most cases.
I also have a Viture One. Image quality on it kinda bad - it's lower resolution and the chromatic aberration is pretty severe at the edges. Also, the way the screen prisms are set up also gets you a reflection of your shirt. But it feels sturdier and the proprietary cable is easier to attach in the dark so it's nicer for travel.
My daily driver is a 2003, I had to buy an aftermarket stereo to get Bluetooth. Recently I borrowed a friend's Tesla for a week, and that was a god damned hostile experience. Shift into reverse - from a touchscreen, mind - and suddenly the entire cabin comes alive with beeps and pings, the dashboard changes to 3 different cameras, none of which show me what's happening to the sides of the car. The 3d overview diagram does almost a good enough job, but is that a trash can, a person, or a telephone pole? The computer isn't sure. On top of that, the blind spots are huge and the back window is tiny and heavily tinted, so I have to use the screens to some extent. If I was my car, I'd have turned half that shit off.
