Second hand information, but one of my co-workers did quite a bit of work at Lever Brothers in Hammond Indiana (plant closed now, I believe). He told me that the detergents are all basically the same but the difference between their top and bottom products were the enzymes added. I guess it's like base oils and additive packs.
I think there was a thread here in the past that mentioned adding a bit of TSP to boost the cleaning power. I've done it occasionally and it does seem to help. BTW, I have the owner manual for the washer (early 90's Maytag) and it specifically recommends using detergents with phosphates.
