Those saying it doesn't matter are probably talking about hop residue being transferred when you are not using a bag to boil them in. For example, I don't use a bag, but simply thrown the pellets into the boil. When racking cooled wort some hop residue goes into the fermenter--no problem there. However, I don't think anyone who recommend transferring your hop sack into the fermenter.
