Discord or Teamspeak or skype

I use TS for many years and there are some of its elements that are the basis and they are not in Discord: e.g. mute and mute on the button. The whole shell with Discord server configuration is great + free. Apparently TS is going to change, it will look like a discord and will allow the creation of free servers for 10 people (maybe up to 3 servers) but still great. As for Skype, it's cool to talk to the cam but people are moving away from it.
