That might be true, but there is no denying that Wasabi coinjoins will be under much greater scrutiny than other coinjoins, since Wasabi are actively paying a blockchain analysis company to monitor their coinjoins and tell them if they have to censor any specific inputs.

I would consider Mercury. There are two reason I haven't yet. Firstly, the last time I looked in to it and downloaded the wallet to give it a spin, I was one of the first and there was essentially no liquidity in the swapping pools, rendering the whole thing pointless at that time. Secondly, I haven't spent enough time looking in to the code to make sure that it is doing what it claims to be doing doing and that the central coordinator can't scam me or compromise my privacy.

The thing about Mercury is that it doesn't obfuscate the history of the coins you receive, but rather swaps your history for someone else's history, and leaves no traces on the blockchain that this has happened. If I'm trading peer to peer, for example, then I want my coins to come directly from a mixer or a coinjoin, so if my trading partner tries to look at the history of my coins they realize they can't find anything. I probably don't want my coins to still have someone else's history attached to them, in case my trading partner looks at them and (as an example) sees they've come from a wallet with 50 BTC in it and then decides I'm now a target to be robbed.
