You mean 3x faster for you, right? We're talking about a geographically distributed system here... for me it's not too different. Or do you mean their DNS servers are somehow by their nature 3x faster than Google's at responding?
No, I mean faster across a broad benchmark suite from 227 globally distributed test locations. 1.1.1.1 is faster in every region - in Africa and Oceania, they're faster by over 100ms on average. It's conceivable that some users could get faster resolution from 8.8.8.8, but highly unlikely.
