NarendraCzarits even more outdated
7777AKASignal is the best.
The thing it’s missing the most is better multi device support and an updated desktop client.
For me, I think Matrix is more complete (specially since it backs-up your chats and media encrypted). The only thing it’s lacking (at least Element specific) is encrypted chat search support on mobile.
What matrix is missing is anyone that I know. Ultimately that is way more important than features in a messaging client.
In my personal experience, everyone who has an account with Signal also has with Matrix. The main issue for me is who has an account at all.
In turn you can bet that who has one on Matrix will have one on Session, SimpleX and at least other 10 apps you’ve never heard about
