The two seem to serve different purposes. I experienced some frustration with 80,000 Hours because I really just wanted to see numerical salary distributions but got lots of words and blog posts instead. I could have set up an advising session, but it felt 1) Cumbersome because I'd need to set up an appt, follow up, etc. and 2) Awkward because I wouldn't trust their judgments to a great extant; they hadn't provided sufficient evidence of their expertise for me to trust their opinions, but I would have trusted them to accurately report data that they had compiled.
