I have had both problems. As it turns out, unsurprisingly, it varies from person to person.
It can also vary within a single person. They might, for example, ask questions too quickly when stuck on a technical question that could be solved by reading docs, but ask questions too slowly when stuck on an ambiguous product requiment that can only be personally answered by the PM or UX person.
