We were talking about this in chatbox and most people agree that teamspeak is better than ventrilo. Also, unlike when we tried mumble, quite a few of us already have teamspeak installed. Features include better sound quality, easy file storage, built in chat boxes, priority speaker, channel commanders (can talk to other commanders across channels), the ability to adjust individual players' volumes, along with a number of management features. Audio codecs available on TS3 range from the lowest bandwidth audio you can imagine up to the superb Opus Stereo Opus Codec with 510kbs stereo sound.
