Netflix - Still the best value for me, so much diversity. Documentaries, movies, tv shows, anime, and a lot of international content.
Crunchyroll - This has been getting most of my time for the past few months since I got back into anime, but it obviously has no value for people not into it.
Prime - I only really have it for games and stuff, and it's only 2 euroes a month, so it's whatever. They have some great stuff though, like Fallout.
Disney+ - I only really keep it because we share the account with a friend, but I'd have probably dropped it otherwise. Currently Shogun is pretty good, but I can't remember what was the last thing I watched on it before that. They also usually fuck us over here with their anime releases where they don't simulcast them and only release them months late.
Youtube Premium - It's a must. It not only enhances the YT experience by a lot, but gives access to YT Music, which means I don't have to pay for another music service. And for the same price as well.
