Not reading you. I joined #Damus first, on May 1, 2023. I was not even aware of #Primal until a few months later, because I was getting my bearings on #nostr as a whole. I am only on iOS mobile, but thought that both clients originated around the same-ish month in late ‘22, (now that I think of it, I don’t remember when I became aware of #Primal).
