TeamSpeak vs Ventrilo vs Mumble

Can some avid gamers tell me which of TeamSpeak vs Ventrilo vs Mumble you use/prefer, and why? Trying to make a business case/get some justification for the investment required in offering the various services to clients -- currently only offer Teamspeak3 and have a LOT of interest, but having spoken to some colleagues at work who game, it seems that it's the least regarded one of the 3?

Only used mumble

Apparently its the one that uses the less ressources from your computer/internet

mumble: celui avec le moins de lag input et celui le plus low on ressources, dans un FPS c'est tout ce que je demande d'avoir !

TS3 is the best overall IMO. I've used all three. TS3 > Vent > Mumble

@ryanghg: Can you tell me what about TS3 is the 'best'?

Thanks for the feedback everyone!

J'utilisait Vent avant mais asteur cest mumble

Sorry for the delay int.

- Teamspeak UI is light years ahead of the other two.
- Server administration is much simpler and allows for more control in TS.
- It seems to be easier to make plugins for it, based on the fact that most games/software I use only support TS.

Only thing going for Mumble AFAIK is slightly less resource intensive and slightly less lag, but I have never had a problem with TS so it does not justify the change (I switched my server from TS to Mumble only to go back to TS).
