Here is a picture of the best 9mm for me. If you compare this picture with other pictures in this thread, you may note that this particular pistol will sit lower in the hand than any of the others, with the possible exception of the Walther. The ergonomic impact of this is that your followup recovery time will be faster than for any of the others because (a) muzzle flip will be less, and (b) felt recoil will be less. Even if the Walther does sit as low in the hand, it is plastic, so the felt recoil will be greater.
