Now, just like cash wasn't built with digital transfers in mind, neither was Bitcoin built with anonymity in mind, so not sure why Monero would be better/worse than Bitcoin for a thing Bitcoin was never made for in the first place.
The purpose of Bitcoin was never that all transactions were anonymous. Monero is great for this (or zCash), but it's a bit misleading to say Monero is "better" at something when what you are comparing it to, was never built for that "something" in the first place.
