Telegram is my favourite messenger indeed.

I don't care much for its stickers but it has a ton of quality of life features. Group chats with topics. Built in translation. Fully supported bots that can add tons of functionality. Voice message transcription. Full access to everything on the web. No problems with bridges (eg to matrix). I'm happily paying the premium fee too which is only 30€ a year. It provides even more quality of life stuff like fully automatic translations (my Spanish isn't the best yet)

Here in Spain it's used a lot especially for groups. WhatsApp is still #1 for 1:1 chats but all the groups (eg associations) i know use telegram.
