here is a comparison of the last two versions of the Wasabi wallet. very clearly you can see how the update to 2.0.4 has increased coinjoin efficiency. there are lower fees for users and over 40% better anon sets for coinjoin outputs.
the whole thing can of course be verified by yourself using the tool WabiSabiAnalyzer
