1.Akashi
2.Aomine
3.Murasakibara
4.Midorima
5.Kise
Idk how to honestly rank them since i've never seen most of them will play against each other, I put Mido in front of Kise because Mido can outlast Kise, as far as stamina goes, if Kise were to keep blocking Mido while he shoots his threes, due to his foot he wouldn't be able to keep it up, same goes for his perfect copy which is only 5 minutes, and Mido spent the whole off season practicing stamina.
Mura is 3 because of his raw natural talent and zone, Aomine is 2 because he is just to fast, like incredibly versatile, kinda reminds me of Kobe lol, and Akashi at 1 because he just sees everything, idk I can't see Akashi losing besides to Seiren because of nakama power, he has perfect rhythm which can put the Uncrowned Kings close to the zone as well.
Overall I find all of them all equal in a sense, while one of them maybe more proficient in one area, for example, Aomines speed is unmatched as well as his ball handle, but Murasakibara is more proficient at defense then him, with his defense area(imagine it in the zone) or Mido is more proficient at shooting then the rest.
