It's more decentralized and anonymized than Signal, but it's not run by a non-profit, and it's definitely not nearly as tested as Signal. Honestly, there's not a whole lot that will get me to move away from Signal as my main encrypted messenger, but I do like to experiment with Session and SimpleX for a little bit of anonymous chatting.
I'd say it's a decent option if your threat model requires anonymity moreso than security and confidentiality. Signal still has the most proven track record and strongest encryption standards so far.

In my country WhatsApp is omnipresent. Not using it means that I cannot even contact customer service or buy from the majority of digital stores because they do not use a land line anymore. Yet, I am the 0.00000001% stubborn without it. I try to bring people to Signal where I have 5 contacts at most. It would be hard to move people away from WhatsApp to yet another platform unless it’s utterly appealing.
Mexico is like this... everything runs on WhatsCrapp, even businesses.
Yeah, WhatsApp isn't great, but I understand why people use it. I just try to convince people who do use it that Signal has the feature set that they're looking for with much better security and they don't have to tie it to their Meta account. It's still better than people using SMS or even Facebook Messenger, though. Unfortunately, a lot of people that I know use both of those no matter how hard I try to get them to join Signal.
Anyways, major respect for holding out under that social pressure. 🫡
Simplex chat also uses the Signal Protocol for end-to-end encryption of messages.
I did know that, but does it use the post-quantum addition that Signal recently created? Genuine question, I don't know.
