I don’t want to see PGP rejection based on usability. So, to level the field at user level we take Delta Chat, which uses PGP. If I understand that correctly.
I have no knowledge of telegram security at all.

Beyond the fact that security on Telegram is a joke (E2EE not enabled by default, only available in 1-to-1 chats, groups chats are all unencrypted, homespun encryption algo), they have never had a full, independent audit of their encryption standard.
It looks like there are a handful of papers that looked at parts of the earlier standard Telegram used (MTProto 1), but nothing on the current version (MTProto 2).

Anyway, long story short, Delta Chat has had independent audits several times. I’d say that says it all, really.

(Also, thanks for introducing me to Delta Chat, was unaware of the project up to now. Neat stuff.)
Agreed.
No audit…then we don’t know.
Have you seen an audit for SwissCows’ Teleguard?
I’ve been testing it for a few days now, after a comment about it here.
They claim to not store your chats, they’re deleted after delivery. To sync a new device requires an encrypted backup from an existing device.
I’ve tested this by restoring a backup from yesterday to sync a new device, and it only has data from yesterday.
That said, I really don’t know how trustworthy they are.
Nice, I hadn’t heard of them until now, either.
I’m just excited that end-to-end-encrypted services have become in such high demand that we’re seeing lots of different implementations.
It took a while, but it looks like Veilid finally has a basic chat built in their protocol as well. It says it’s secure, but I can’t find any info on its particulars.

Meh. I only read a translated version, so it’s hard to tell nuance.
But nothing in there is inaccurate. Maybe overstated.
Personally Signal seems trustworthy, but… I have some ambivalence, given their bullshit reasons for dropping SMS support. They claimed it cost them engineering, which is at best wrong, at worst a flat out lie. Signal has nothing to do with how SMS is managed - it merely hands the message to Android’s SMS system. It’s trivial. So why would they drop support and use that lie?
When I’m being misled, I start to look at everything else as having a bit more validity.
Plus UI/UX on signal sucks. It’s no better than the lamest SMS app. Hell, old SMS apps are better. And no multi-device sync. They claim it can’t be done and maintain encryption. Right. Clients just need to use the same encryption key…like Telegram does, and now Teleguard - and they’re claiming full e2e at all times.
