Telegram is just actually superior in terms of features I don’t get it.
I’d rather push for XMPP personally, the matrix protocol has been a dumpster fire in an “almost ready, trust me bro” state for as long as it has existed, and failed to justify its own weight and complexity. But that’s mostly irrelevant since they are open protocols and can somewhat bridge with one another.
I’m selfhosting a Matrix server and have all my Chats from other apps also bridged to there. For just text chat I don’t feel like Matrix is missing anything, the thing preventing me from getting my not so technically minded friends on it is the missing support for good group voice chat.
It XMPP better for group VC? Is the option available to bridge Messenger like Signal, Telegram, WhatsApp, Discord, iMessage to XMPP?

Same here, but with XMPP in place of Matrix. For historical context, XMPP was invented about 25 years ago on the premise that people were already tired of having their instant messaging scattered over multiple protocols (rather than Signal, Telegram, WhatsApp, Discord, iMessage now, it was Yahoo, MSN, AIM, ICQ, … then), so bridging is very much front and center in the XMPP world. Over time, people also realized that bridging sucks in general (you either dumb down your client to the lowest common denominator which sucks for yourself, or your client isolates itself from the source protocol enough that it sucks for everyone else).
To add insult to injury, most modern protocols also forbid, by their ToS, the use of alternative clients (which very much includes bridges), and to the best of my knowledge WhatsApp, Signal and Discord will eventually suspend your account on this basis.
Matrix is still trying to carve a niche for itself in this space, and is failing IMO (judging by the quality/security of the bridges they have come-up with, and the recent libera.chat fiasco). I’d say that the situation in this regard in XMPP is only marginally better due to the fact that XMPP had a decade headstart to fail and try over, and I would not recommend using bridges on either of them if that can be avoided.
It XMPP better for group VC?
I’d say “it depends”. Fun fact, Matrix uses jitsi-meet under the hood (which is XMPP + a media transcoding/multicasting component that doubles as a relay), and jitsi-meet is my recommendation for this use-case: as long as the central server has good bandwidth, you can really scale up your VC to many attendees. On top of that, XMPP has support for peer-to-peer group VC, with the benefit that hosting is simpler, it doesn’t require any central component/relay (but the bandwidth cost is incurred on all participants and you won’t go beyond a handful of attendees that way).
