I like gtalk much and skype for instant messaging and conference. I really do not like Yahoo Messenger, it looks very clumsy.
I also see skype very good, especially with skype file transfer error free as yahoo,and to use skype video call is really cool
Ibibo messenger is better than Yahoo and Skype. You can also chat with your facebook, msn and gmail friends from ibibo messenger. No need of any others. At first I was using Yahoo! and Skype. But now-a-days ibibo. #High quality Video chat with slow internet connection. #Confercing audio calls #Chat Rooms(Hot Groups) #Screen Captures #Play Audio/Video file for contact #Fastest File transfer #Remote Support #Nudge,Emoticon,Magic Emoticon #Online Games,etc...............
If you're using the chat rooms feature, then even i can't keep any comparison with other service. But, if you're only talking about messaging then I'd use Gtalk as my second option to IM.
Yahoo Messenger !? Skype !? GTalk !? come oooon... I read two pages hoping I will find that old school chat that we all started with.... ...remember mIRC ?
Skype is better for more function than yahoo. But i support yahoo very much then skype because its have more service.
