To be fair, Ublock Origin is a lot more common, and the less extensions the better, so or a lot of people this would be the better way.
You can also just use Tamper Monkey (though you need to add a script called Trusted Type Helper in order to inject CSS into YouTube).
I used to use Stylebot but I switched everything over to Tamper Monkey so all my CSS and non CSS related scripts would be in one place.
Tamper Monkey/Grease Monkey scripts are very portable too, I use my scripts in Safari on iOS via the UserScripts extension.
