Objectively better than the garbage the GP mentioned but objectively worse than Telegram. After using Telegram for work at my previous job, switching to slack now with a new company is jarring. Their absolute dogshit electron apps constantly hog system resources and take forever to load. Also Telegram is free and has a far better audio and video chat and again, free... I find it mind boggling companies pay for chat. Both discord and Telegram provide all the same features, incl bots and do so for free, what gives?
