It's a fair question - there can seem pros and cons either way. Generally for people following the AffiloBlueprint course its recommended to get one site earning say $50 a week before expanding to other sites to replicate their success.
If you have one big site and its extremely broad i.e. covers completely different niches you might find it hard to rank for anything in particular even if use siloing.
Search engines will index the entire site looking for relevancy and keyword density to match a users search - and if your site doesnt have focus it may not feature high up in the rankings.
