Yes it matters, Those that say no clearly don't know much when it comes to hosting & domains. I like full control over my domains which is why I mainly use NameCheap, they provide whois protection, nameserver protection and more for free.
For instance, don't buy from a host that's not been around long, they always tend to close after awhile. Most hosting company's that provide domain registrations charge extra for nameservers & whois protection, whilst some even require you to contact them to change them.
Not forgetting, the pricing difference each company offers per domain extension.
I usually go with NameCheap for all my domains as they provide realistic pricing & domain coupons. Otherwise I'd use 1&1 for their 99p domain registrations. I did use GoDaddy once because that's where the domain I wanted was currently purchased with, unfortuntely for me, their domain system was too complicated for me, especially when it came to switching nameservers.
I could go on and on, but it's more or less your choice who you go with after abit of research. Just don't do what I did when I brought my first domain all them years ago and go with the first website you see, boy, was that a big mistake.
