I really like the Tide Pur clean for my darks. I haven’t used seventh generation in years because I was unhappy with it’s performance back then. So I can’t compare to their current formulation. Pur clean does cause more suds even in our hard water but I’ve never had a suds error.

^^ My local grocery is clearing out the Pur Clean as a last chance item -- wonder if it's just not a good seller and it's going to be DC'd. They only had the lavender scent left so I didn't take advantage of the clearance.

I have the same experience that Dslane78 has had. More than likely will switch to Tide Ultra Stain Release and use an extra rinse to try and remove some of the optical brighteners instead of searching for another OB free detergent if it is discontinued. Kind of a shame.
