This is actually the reason I said "Just use Cinny"
So in a way, the answer's sort of because "I am saying so" but as with all things the answer's subjective but I hope that you can try matrix and enjoy the clients that you wish.
I would recommend you to "Just use cinny", Just try it once and have fun :D See what you like the most and then recommend it then instead to your friends/community.
I am gonna say, Just use cinny but you can say just use fractal and both could be valid and the beauty of the protocol in this sense is the fact that we can all still talk to each other :)
Cinny really fixes the UI/UX problem in my personal experience, even better than discord.
And y'know technically this problem still persists with other messaging protocols like how should a new user know they should use X client and the limitations of X client (UI/UX). Matrix as such meets half way through and cinny can then streamline the experience.
You or anyone using matrix doesn't have to know so much.
The only thing one has to know is "Just use cinny" (in my honest opinion) and everything else is actually really simple.
And I feel like new users like any new users of any tech (discord was once new too) knows simply because the time is convenient/somewhat mouth of word.
I feel like people should convince others to meet on cinny (matrix) because then we can have network effects which is actually a really big issue in my opinion.
So the answer's mouth of word. I hope you can spread the word and hope that you can try cinny. It's seriously that good and I am doing my best spreading the mouth of word.
