Ah my apologies. I'd say Brave out of the box then. It has Google's DRM blocked by default and I would see them continuing the trend, making it more opt-in. Time will tell.
Brave for the compatibility with websites (because most website designers are testing against Chrome), out of the box it's hardened for privacy, and we'll play DRMed content when you need it to.
Though I have heard nice things about Vivaldi as well. I may look at that in the future.
