A very important reason why I will continue to use namecheap... when a domain of mine expired, it cost me nothing to recover it via namecheap. I had a similar experience with a domain I had registered with godaddy expiring and it cost me $90 for the same recovery of a domain name. I transferred my remaining domains that I had on godaddy to namecheap and haven't looked back.
Similarly, I had some domains which had expired for 2 days, and Namecheap let me renew them at no charge. I am pretty sure at GoDaddy the same thing would have cost at least $10 extra(wouldn't surprise if it is actually $90).
On the other hand, GoDaddy renewals are roughly $3 cheaper than Namecheap, because many GoDaddy coupons work for renewals, but I can never find good coupons for Namecheap renewals.
