Internet Brands (the parent company of vBulletin) and GoDaddy are both owned by KKR.
So GoDaddy is like vBulletin's Uncle...
And I have had excellent results and service with it, used it for over ten years now. I host four sites with it and pay only $150 annually for unlimited storage and bandwidth.
Only trouble I ever had was recently, on one of their windows machines I inherited after a site purchase. Migrating the vBull to Linux fixed the problems.
When I set up my forum in Sept '14, GoDaddy didn't have the necessary PHP requirements for VB5 (On the cheap subscriptions). They may have now, but that's why I went with Siteground instead of GoDaddy and am actually glad I did..
GoDaddy is excellent if you are managing domains. I manage my domains with them, but I NEVER buy hosting with them. There are some scripts that for whatever reason have issues only on GoDaddy hosts, not vBulletin but others like MediaWiki. Or at least it used to be so with MediaWiki. GoDaddy is usually a shared host and its a lot of times very slow. If you have a forum that does not have a lot of posts, members or traffic then GoDaddy is a great option. There are actually other hosts out there that are shared hosts that are cheaper and work just fine.
