I moved all of my domains from GoDaddy to Namecheap. I host my own DNS. Recently, I decided to take a stab at implementing DNSSEC, but one condition is that your registrar must support it[1], and Namecheap doesn't[2]. I'm in no rush, but it's a little disappointing. I have no idea if DNSSEC is an option when Namecheap hosts your DNS. They've also only recently added support for IPv6 glue records. Nonetheless, I'm happy to be rid of GoDaddy and find the Namecheap interface to be much simpler and easier to use (concise email notifications of logins and account changes are also nice, and readable in more email clients than the noisy upselling HTML garbage that GoDaddy spews out).
