Signal has probably the worst UX of any messaging app. It also used to require sharing phone numbers to add contacts, which imo is already a privacy violation.
Telegram is fast, responsive, gets frequent updates, has great group chat, tons of animated emojis, works flawlessly on all desktop and mobile platforms, has great support for media, bots, and a great API, allows edits and deleting messages for all users, and I really like the sync despite it not being e2e.
