But a nice 65" OLED TV is still cheaper than a Vision Pro, so I can't recommend it unless you are in a situation where you literally cannot put a big OLED TV in your space, or you're desperate to take your OLED TV with you on flights.
I also have a Quest 3 and without OLED for true HDR, it loses right away, and then it loses further on resolution. Audio quality is really good on Quest 3, but... If I really wanted to use a headset to watch a movie, I would use the Vision Pro, hands down. If I only had the Quest 3 on hand, I wouldn't watch a movie.
