What's your "the best"? USD is certainly most popular.
That's what Unit of Account is. The one that's so popular all goods are priced in it.
Bro, any accounting package will let you choose any fiat denominator you like. The good ones will let you choose any commodity as well.

https://en.wikipedia.org/wiki/Unit_of_account You'll find Bitcoiners far more knowledgable than typical normies on this one.
That isn't what a Unit of Account is dude.
Bro, you need to school
I'd be happy to see other units of account in niche circles. Hey maybe I'll participate in said niche circles even. They just might catch on. But there aren't any.
I love buying things in BTC or XMR. prices may still be denominated in USD originally but it's a good first step. as communities become more self-reliant and not needing to interact with fiat as much, they can start to price goods purely in what they themselves value.
Here in Australia, publications always use AUD. In Britain its the pound. BTC or gold would be my choice. Maybe XMR if the context is DNMs.
While it's true that you can have local units of account they all come back to the USD. sorry Australia. We can certainly argue that exceptions are made for countries that do not participate in the United States dollar homogeny. You mentioned BRICS. I think there are some nuances there, but basically you're right.
