While the naive per round privacy expectations from Whirlpool are objectively smaller than WabiSabi (5 input minimum in Whirlpool compared to 150 input minimum in WabiSabi), that's just an implementation detail. There's no coordinator fee charged for remixing using zkSNACKs' WabiSabi coordinator either.
The advancement that makes the WabiSabi coinjoin protocol so much better is that you gain COMPLETE privacy on your coins, whereas Whirlpool links your transactions together due to common input ownership being revealed and toxic change being created during the premix transaction.
WabiSabi coinjoins gives the same privacy UX to Bitcoin as Monero does to Monero 🎭 The only exception is if you are the largest whale in your coinjoin round - since Bitcoin does not have confidential transactions, a whale's coins might require multiple remixes before gaining full privacy.
