Yes and no. Hard to put it simply... You see sometimes adjectives can use both, sometimes they don't go along well with one of those:
e.g.
как долго - kind of alright
насколько долго - nah... not good at all, at least without a context that'd call for it.
Same goes for your examples:
I like the one with насколько, but kind of scoff at the latter, although it might be okay to use it like that.
