0xChat vs Keychat vs SimpleX ?

Any opinions on which one has the best security and privacy?

Spent the last six months putting people on SimpleX. If 0xChat or Keychat are better, I could try to convert some people. I told everyone that SimpleX was simply the best tool at the time but privacy apps built on Nostr might be better later. Are we there yet?

My understanding is that with Keychat, one needs to pay sats to chat. I'd be willing to do that if it's the best security and privacy model. But not sure how well that would go when introducing normies. It seems to me like it would slow down adoption. People can just run their own simplex relays for their private group so I'm not sure the economic sustainability argument by Keychat checks out. Dunno.

Opinions?
