Wibiya or Meebo for Xenforo Forums? Which one do you prefer?

[surfsup]

Some people like them some dont...but I wonder in your opinion which one would you install?

Does it slow down the forum at all even if on a dedicated server?

I am thinking it would be good to have it for Chat, sharing content, liking Facebook Fan Page etc.

Your thoughts?

actually just found out meebo is canceling a lot of their services since google is taking them over..
