I can't say as I notice a difference in results in my own machine, so unless things actually need a 60 wash for any particular reason I stick with 40 for most clothing. I appreciate you've noticed a difference in your own clothes, and also that you're stating it as your opinion, but people who state their own opinion as a fact and a "must" do irritate me. Probably my science and stats background wanting empirical data and evidence.
Anyway, as I say in my own machine I don't notice much difference. In fact, I've seen whites come out of my machine on 40 looking better than some that have been washed at 60 by other people. Suspect this is due to detergent dosing, or knowledge of how to not overload machine, or any number of other factors.
