So, for forms of web-based and internet chats Discord is on the top now days. Guilded is creeping up behind. Team speak went out years ago, and is still such a horrible platform. I unfortunately still utilize it with my FiveM RP servers that I play on.. but I truly hate it and its permission base system. Its easy once you understand it. but still a PITA. Discord is simple, easy, and looks good. It servs it purpose and bot integration is so useful with it. Cant beat it currently.
