I prefer to use coinjoins with Sparrow wallet or JoinMarket (I don't care if coinjoins take a longer time; I can separate short-term from long-term coin use; what I want to make more private by coinjoining are rarely coins to be in a hurry with).
I hit this milestone in Sparrow a few weeks ago, and decided to screenshot it for posterity:
I've added a few more to that count since then, and I've got a couple of such inputs in the same ballpark. It's turned in to an experiment now where I will just refuse to spend at least one of these outputs unless absolutely necessary just to see how high we can go. With every remix after the first completely free, of course.
I lack the time and coding knowledge to do my own research and code audit on Wasabi.
You don't need to. The freely admit their are cooperating with blockchain analysis and directly funding state sanctioned surveillance and censorship. That alone is more than enough to mean nobody in the right mind should ever use Wasabi.
