While I won't say that Monero offers heat privacy, it's clearly much better than CoinJoin or JoinMarket on bitcoin. For one thing they have thousands of users and transactions. The number of people participating in mixing gives you a big shield to hide behind. For another, they hide balances, and they do actively pay attention to the information leaks, and they employ strategies to fight that. When the drug markets were busted, dash and pivx users were discovered, but Monero users were kept hidden. It's pretty clear to me that they are at least moderately successful where nobody else really is yet. New strategies may come out tomorrow to unmask everyone, I certainly wouldn't bet my own life on Monero's safety, but they overall are outperforming everyone else in a practical sense.
