Is it? My experience with it has been middling at best, and I communicate with exactly zero people through Matrix outside of the context of open source projects. The UX is still pretty bad, with many rough edges around sign-in and device verification. The message/encryption story has gotten better (it's been a long time since I've gotten spurious errors about being unable to decrypt messages), but it's still not particularly easy to use. Performance-wise I've found it to still be fairly bad; loading messages after I've been offline takes a noticeable amount of pause, something I rarely see with other messaging platforms. On the plus side, Matrix does have many chat features that many people like (or even require) in a chat platform, like formatting, emojis, message reactions, threads, etc.
