BMW S1000R vs Kawasaki Z1000

Servus, as you can already conclude from the title, I am looking for a new motorcycle, I want to buy it again, the BMW S1000R and the Kawasaki Z1000 are available to choose from. I started with a CBR600RR, then switched over to the Fireblade and now I am looking for something new and more comfortable. My Sozia never had problems with the Fireblade and also really liked to ride along, that should not change with the new machine. That’s why she should be cozy r as the old one, which definitely shouldn’t be a problem As I said, I have now shot myself on these two machines since Yamaha with your MT-10 needs unfortunately still some time until this then comes on the market. I would be happy if you would share your opinions, reviews with me and would support me in this purchase already many thanks to all of you.
