As someone that has friends on every chat platform out there, I must say that Telegram is the most polished chat app in existence. Everything just works. I notice bugs in WhatsApp all the time, but hardly ever with Tg. Even stuff like video chat and video messages has always been reliable and fast. As a developer, the API is amazing... in 30min you can make a bot and publish it. The real shame is two fold: chats are not encrypted by default and there's so. much. bot spam on the platform. These two problems have made it my least favorite platform, even though the usage experience is the best.
