Namecheap all the way. I'm not even swayed by Godaddy coupons any more. I've completely stopped using them.
We can find out that namecheap currently is trying to overtake godaddy with providing cheap domain name as well. So i believe namecheap will be better.
NameCheap is one of my registrar's of choice. I like these ease of purchase and transfer to my hosting. I stay as far away as GoDaddy as possible.
Hate to have some stuff stuck with Godaddy but I did not have the funds to join the mass exodous.. http://tech.slashdot.org/story/11/12/25/1452251/go-daddy-loses-over-21000-domains-in-one-day if you don't know what I am talking about you have no business being on the internet. Nigel
Been using Namecheap for all of my domains as of late. Love the free WHOIS and promos they run regularly.
I prefer namecheap although when I owned warezscene.net which is currently sceneflux now, a friend of mine used their live support to ask namecheap why the site was under investigation per court order, and the agent willing released my information to a stranger. Very un-pro imo.
I use namecheap to register my 1st domain name. After that I try godaddy when they hv offer at 1.29USD/year for new registration. currently I am using yahoo to register new domain because only $3.95/year (1st year $3.95, 2nd year suck your blood at $34/year, so, trasnsfer it out)
I like to look for domain variations by using the bulk registration tool on GoDaddy and then registering the good ones with Namecheap. I just don't like how GoDaddy runs their business.
