eos666 I changed from Pico 4 to Quest 3. Actually I had both for few moths but noticed I prefer Quest 3. I used Pico 4 only when Quest 3 was out of current and was charging 🙂 Then is decided to buy headband with battery pack and sold Pico 4.
Main reason for me were PT and better lenses. Using Pico 4 I could see individual "pixels", good rays and some image warping. Those were really annoying, especially latter warping. Like some black hole in front of picture delicately distorting everything. Using Quest 3 all are pretty much gone. For me visual quality improved, but it depends from person to person. Some did not see any warping or screen door effect using Pico 4. That souds weird.
Actually you will loose some FOV using Quest 3 🙁 That's is the only negative thing. I really liked Pico 4 because of larger FOV and better lens overlap (no binocular feeling). You can get larger FOV by using Quest 3 without face cover by means of buying Bobo VR S3 Pro head strap. Worth every penny.
You don't care about passthrough, but that is definitely future in VR porn. The problem is that you have to find the right videos. Let's say only 5 % of SLR content is good and only 20 % of that content is suitable with PT (right position, angle etc). Actually you have to use BYOJ (build your own journey to cut videos perfect) to make it work. So quit time consuming but when everything is ok it is 100% pure gold. Beats everything and is like heroine. After that you don't want to watch anything else.
PT is far better in Quest 3. Consider that as an option. I hope this helped.
