nameservers...

[Annoyance]

hey everyone,
got a noob question, very ashamed, but here goes...

is it better to use my registrar's nameservers (namecheap) or my host's (valcato, well not yet, but soon)?

i understand what a nameserver is and does, but I don't understand what if any are the perks/problems of using my registrar's or my host's...

any help would be appreciated, thanks a lot...

I think it is better to use your registars. They are very reliable, so if your host was ever down, you could foward your domain to a page that notified your site visitors of a problem instead of just having your domain come up iwth an error.
