First, YouTube doesn't even offer Premium in my country.
Second, the features of YouTube revanced apps also just simply surpasses official app for me anyway:
- My phone has 1440p HDR display and YouTube official app just doesn't show me above 720p60 for 60fps videos while in the past it could. And it put me in an awkward situation: for under 60fps and for HDR 60fps videos, it can show up to 2160p and 2160p HDR 60 fps like normal. The only videos that cannot go over 720p60 fps are the normal 60fps ones. I don't know what the actual bug they are introducing there. YouTube revanced extended works flawflessly.
- I can hide the sections I don't like (news, shorts, suggestions for me, mix playlists, the ending overlay at the end of videos... and many other things).
- I can swipe on the screen for brightness and volume.
- I can add the copy buttons that copy the video link AND the timestamp quickly, really convenient for me.
- And many more that I'm lazy to type on phone.
Those small features (except the first one) look like something I would laugh at but one by one they surprisingly enhance my experience with YouTube app a lot.
