So which one is better teamspeak or skype?
"Better" is a big word.

I have tried both and they each have their pluses and minuses from my perspective.
TS: You get Susan (who often plays Moonlight Mcboo), Chanty (Kippy), Sheriff Tricky, apparently Elga now and many other experienced players. Lots of good advice going around but I found it hard to actually talk about the battle going on. I felt there was too many people together to make it useful for battle. But still fun to talk to a good group of people. (Well, I never actually talked to Elga, is he a good person?

)
Skype: So far only 3 of us, Susan (Sally B) myself and Judy (Pinky). Obviously the issue of a large group hasn't happened (yet). But I also think that would be more manageable because we could break off into our own conference calls depending on which group we ended up with on a run. With TS Chanty needs to break us off into rooms if that is to happen. I like being able to self-manage and not put a burden on someone else.
So, obviously I'm skewed towards Skype, especially for battles. I would be just as in favor of Statics Connector if it works right away (haven't had a successful test yet) and if I can self-manage as in Skype (which I'm pretty sure I can).
Hope that gives a broader perspective on it.
