I'm surprised you only got 6 different opinions!
Individual tanks have different requirements. What may work for one person - and be the basis for their opinion - may lead to disaster for another person. You just have to weigh all the different opinions, understand the "why" of what they're doing, and make your own opinion.
My opinion, based on my tank... weekly 10% changes, or 20% changes every other week.
