GoDaddy is suitable for someone who has few domains.
The interface is one of the worst in the industry. Customer support is lacking.
Their attitude towards domainers is terrible. They are known to hand over a domain at the simplest request by a complainant, sometimes without a court decision. They interfere too much in the domainers business and cannibalize their own resellers by competing with them.
the only plus side is the pricing which is merely 'ok' with coupons. Their features offered for domain control are pretty good.
everything else is below average to bad. Not to mention tdnam, but that is a different story...
