Best tire for precise steering and feedback?

Hello together, I had last installed on my BMW e60 Michelin Pilot Sport 3 (245 40 R18 93y) and with those, as well as with my Conti 850 winter tyres in 17″ is unfortunately the steering a little spongy around the middle position. I am now looking for a summer tire with which that is better. I was now close to ordering the Pilot Sport 4 with load index 97. The PS4 should not be based on my PS3, but on the Pilot Super Sport. And this has a very good reputation as far as steering precision is concerned. From the higher load index 97 I hope that the tires are even stiffer and thus give more feedback in the steering. However, I have read in several places that the Continental Sport Contact 5 should have such outstanding steering precision. And now I am no longer sure if I should rather take the, or the Sport Contact 6. In terms of comfort, the PS3 93Y was more than enough, because I am ready to make compromises. I am really feeling better about everything. Does anyone have a tip for me?
