I am use both but name.com is very good and best for me, namecheap is also good. I don't like godaddy, lots of scams.
godaddy is great I have used all major domain registers and I prefer godaddy hands down great prices great service and great support and if you sell domains its much easier to sell a domain registered at godaddy in my opinion
It depends. I flip quite a few domains, and because of the number GoDaddy customers, it's hard to sell domains at auction without them being on GD.
I use Godaddy ant don't have any bad words about them, they provide me all what i need. Thier service, quality and more...
I would choose GoDaddy. They give alot of free features with every domain name purchase. You could also try GDI Web Solutions.
Internet marketers sometimes have troubles with godaddy, but I've only had problems once, and it took 20 minutes to fix, and I've been happy with godaddy overall.
Name.com is better (though I use both) they have fast support, good customer service, good interface. Though godaddy's pricing is better.
