Teamspeak is still the best when it comes to chatting when gaming, it is usable with voice activation, push to talk and it has so good echo cancellation that it works when both of us are on speakers.

Though the current version uses almost a full core on my machine, it's still worth it in my opinion and you can find many free servers you can connect to.

We switched to Mumble way back when I played Cod2 competitively. It was better in every way.

Ventrilo was "meh" (probably between the two).

Edit: Fixed product names.

I tried Mumble but it was lacking in something, maybe the push to talk did not work properly or the echo cancellation was not working? I can't really remember now.

Teamspeak used to be the best. I used it for a decade. It's only within the last couple years as they've tried to become Discord that it's started going downhill. Teamspeak 3 was solid enough but soon they implemented the artificial lifetime, you had to re-authenticate your server every year (and sometimes more often). Then they got rid of the old forums and wiped everything clean. It hasn't been the same. I stopped using TS recently.

I do use matrix, but only because of the pandemic. And matrix itself only does 1-to-1 voice. For multiple it has a system to shunt you over to jitsi and autoconfigure the room. So I don't see how TS5 is going to use matrix.
