Trust tyre label or adac tests?

I’m looking for a new low-cost summer tire in size 175 65 R14 for my car. Now the ADAC test 2014 , 6 pieces are listed as particularly recommendable, and 2 have come into the tighter selection. But now I’m surprised, for example, the tyre label from the falcon has got an A. ADac tests it worse than the Hankook , and the adac better hankook only a B. Hankook Kinergy Eco K425 -> wet brakes Adac: 1,9 , tyre label wet brakes: B Falken Sincera SN832 Ecorun -> wet brake adac : 2,2 , tyre label wet brakes : A on what should the customer be able to rely now? p.s just see that the matures at another online shop also have other reviews. Since the hankook has once again only one C when wet braking.
