Wire uses the same encryption protocol as Signal. (they changed it to that after version 1.x, many years ago).
Wire has more features than Signal.
Wire does not force you to bind it to your phone number (you can use an email instead).
I have used Wire in the browser, on Parrot, without any issues (except that’s not a suitable substitute because the browser version does not keep chats history/content when you would like it to).
Wire is definitely not slower than other encrypted apps like you suggest - it is no faster, no slower, than using Wickr or Whatsapp.
Regarding development - Wire has a very active development team (they have the resources).
The app is independently peer-reviewed every 6 months. How many messengers do you know of that are audited so often?
As for Telegram - it is not considered a “security app”, because it has no encryption for most functions. Therefore not a viable alternative (so of course it’s going to be faster, without encryption!). That’s why the title specifies “secure, encrypted messengers”. Telegram has no encrypted chat-rooms. One-on-one conversations are by default not encrypted - yes there is an option in 1-on-1 for “secret” mode, but it is an extra task - you have to remember to manually turn it on each time, and even in that mode, media content and files are still not encrypted (last time I checked).
Russia didn’t ban it because of it’s optional encryption in 1-1 (which is reportedly flawed), but because it makes it easy to organize protests - and Russia wants to continue to control it’s “democracy”.
With Telegram, you have to be careful when reading on their website - they are intentionally vague and omit key information - even most native English speakers don’t detect the subtleties in their wording.
Wire is far more transparent and up front about things.
