I'm not sure that Slack is a proper term of comparison for Telegram. A closer competitor would probably be WhatsApp, and Telegram Desktop easily beats the "desktop" version of WhatsApp on every single aspect. The only reason I'm still using WhatsApp is due to the fact that that's what all the people I know use.
