It depends on many things, such as a threat modeling, opsec, etc. In terms of privacy and security !simplex@lemmy.ml seems to be superior.

Several reasons to that:

• SimpleX doesn't have IDs, unlike Session. Which makes it more anonymous and private;
• Ofc things like E2E encryption, forward secrecy and others;
• Message mixing is and underrated feature, as well as content padding;
• It has amazing security features such as self-destruct passwords, and a couple of others;
• Can be self-hosted;
• No need for phone number;
• Leverage several 'accounts';

I have read their white paper, and is worth the time. Also, one of the episodes of the Opt Out podcast is with the SimpleX creator. I suggest listening. I personally liked the way he conceptualizes decentralization, and problematozes protocols.

I found SimpleX to be the best of all private messengers. Better than Session, Signal, XMPP, DeltaChat, and others. It is also more convenient than Briar and Threema.

You suggest luring them away? Did you implement this solution?

I personally suggest Tuta (and I use it daily) over Proton. Several reasons:

Proton:

1. it is leaky in terms of social graph encryption. Sun Knudsen has a great video about it (https://youtu.be/GdDFUycXR_M&t=0)
2. had this case about the climate activist (https://www.theverge.com/2021/9/6/22659861/protonmail-swiss-court-order-french-climate-activist-arrest-identification). And since they position themselves as a privacy company, this looks disturbing.
3. I'd prefer a such a privacy oriented company to be more open to anonymous payment methods.

Overall, Proton seems like a little more privacy-conscious Gmail alternative.

Tuta

1. doesn't use Google/Apple notification servers
2. encrypts more stuff than Proton

PS In both cases, emails are not end-to-end encrypted. Even though both are marketed with E2E encryption by default. Again, Sun Knudsen has a great video about the topic (https://youtu.be/G2Jh8bQ2wM8&t=501).

Also, as far as I remember, Proton is more expensive while having less features (the cheapest option) than Tuta.

Film is a nice, up and coming company. I tried their services, all works. Client-side encryption is definitely a great feature. The downside for me was how the iOS app literally kills the battery.
