You all got a valid point… it’s just that mileage varies and x codec will sound better in y combination. If I remember right, AAC on Android is at times implemented differently than on it’s home Apple: The encoder would work with smaller bitrates to save battery. There must be a special synergy for max bitrate LDAC to sound worse than AAC, indeed. All in all my post is about being open minded and giving you the option to use a thing, rather than finding out what codec is universally the best: You virtually can’t, can you?
Pihole, if i understand correctly, works by blocking DNS requests and YouTube ads are not DNS based the way ads usually are. You’re stuck blocking them by uBO on each device or use Invidious.
