Adoption is important, isn't it!
My answer is... Coinbase.
Sure we all love to hate Coinbase, But "the rich get richer" as they say. A big company, with a big brand, and a big twitter account -- they advertise, they lobby in Congress. While everyone is out there tawking about nothing. Coinbase is making money. So every year my answer would probably be Coinbase.
If it isn't Coinbase, it would be one of those companies I see when I land in the Swiss Airport. Anyone who advertises. Those people are serious about adoption, and the rest of us are just larping. This is the tragedy of losing BitPay during the blocksize war -- getting that little Sticker on every payment terminal would have been Bitcoin's #1 biggest win. Instead that plan lies in shambles.
Clearly, the ordinals people gave us a big bump in actual node-running users. So they deserve special mention since node-runners are the truest Users of Bitcoin.
