-- short update about Wire --
I am using the desktop client, described as "experimental binary" on the Wire
website where the deb file is available, but it has proved completely stable
in my experience to date. I have been messaging with people also using
desktop clients, most probably proprietary ones.
In my own user case, the obvious advantage of Wire is to be able to use
end-to-end encryption from my laptop while Telegram only provides it as an
option called "Secret chat". That option seems to be available on the mobile
device linked to the user account phone number only. Wire does not ask for a
mobile number but for an email address on which the account is based. I have
not tried yet to erase my account and create a new one using the same email
address but it might be possible.
Wire is doing fine for text messaging (no bundle delivery, decent delivery
time), transferring files and displaying pictures "inline". The interface is
clean and, as mentioned abobe, the GNU/Liunx 64bits client is stable. It is
more sober than Telegram in terms of emoji, stickers and all that jazz.
Though syncing is not compatible with end-to-end encryption, it is possible
to archive conversations and tansfer them to other devives.
