What VOIP client do you use?

just wondering what people use or prefer over others.

i am currently using Mumble.

used ventrilo, teamspeak and used skype for a bit.

i like ventrilo because its lightweight and easy to use but have had allot of problems with it and my friends have had similar problems with it lagging out on certain games. that made me switch over to mumble becuase of some good reviews i read. and i have to say, its pretty fucking good.

easy to used, sounds quality is the best i've heard, and it works.

although i still have to use TS and Vent because of joining to others channels.
