Matrix/Element's UX is abysmal, it's not a viable alternative to anything. I continue to get 4 popups (two of them modal) every time I login, and I have to login every time I open it because it doesn't remember logins. And it happens not on just one system, but on two different browsers on two different PCs.
The only even close to being something I could let my non-techy friends or relatives use is FluffyPokemon or RainbowUnicorn or something like that.
And even it's still missing features.
Cinny (https://cinny.in) is the first Matrix client that actually looks promising. They just plain stole Slack's UX and it's working. There's no need to be unique for the sake of being unique when it comes to UX.
