My experience with deo streaming on slr is pretty great, I use quest 2 and Pico 4, picture wise it's looks decent to me, and i don't even use the highest file, i use the 3360k file, also I like how deo with slr I can skipp forward easily with hardly no loading time, I used Playa before for streaming but it would load to long when skipping forward maybe they fixed it now but also hardly no other sites worked on there for streaming.
Hs is good, I used it for Lil bit with my local files, but idk 🤷♂️...really did nothing for me, deo just more convenient for me.
And FYI in hs what ever stream or if you visit a page with thumbnails pics for sum reason all them titles will be in your recent watch history, I found that one day and was like wtf I didn't watch all these vids, yeah so you gotta clear it out if you don't like that kinda thing.
Might of been a glitch at that time maybe they fixed it now.
But deo player is my go to player, I just wish they roll out that smb support cause it's hard for me to stream from my computer to deo. Smb works way easier. Imo
