The weird thing about this is for me it started working just fine with both micro block and noscript. Sometimes there's a delay but otherwise no ads

+1 for Grayjay, not the most user friendly out there, but once you get it setup it's really good!

I use uBlock on PCs, Revanced on the phones, and SmartTube on the Firesticks.

At that point I bet they will block any browser or device that is capable of blocking ad banners, let alone Youtube ads

Never heard of it; I'll check it out, thanks.

(Is it like PiHole? Not a fan of that because it does a bad job at blocking anti-adblocking measures, while everything else I mentioned defeats them every time, especially UBO.)

Fun fact: if you pay for Amazon Prime Video, most of their catalogue is actually on Freevee (which they own so you can access it through the same TV app) and you get shown an ad every fifteen minutes anyway. And even on the shows that are actually on Prime and don't have midrolls, if you pause the TV show you will see a fullscreen ad instead of a freeze frame until you hit play again (except that there is a handy prompt informing you that if you press OK instead of unpausing you will be taken to a page where you can order the product shown directly from your TV)
