I have a few domains registered with Yahoo, and it beats goDaddy by a mile. Yahoo Domains offers superior customer service, the operators are very friendly and helpful. If you purchase a hosting plan with Yahoo, they also give you a free website building tool, Yahoo! SiteBuilder which is also great. I completely trust Yahoo, and they hardly ever have glitches in their system. Domains usually become active in 1-2 hours, as where with goDaddy, they usually take 1-2 DAYS to get your domain up and running.
