I think most people would agree with me when I say that TeamSpeak is kinda outdated now, Discord is better in almost every way, Servers don't need to pay/host teamspeak servers(though in fairness those servers didn't cost that much anyway), and players don't need to install any client to be able to talk with the friends.

Agreed, I think the biggest factor with Discord is that it's a lot more modern & easy to use. From phone apps, Windows app & even on your browser it just makes it 10x easier to use compared to TS3.
