From weakest to strrongest:

Shoyo Hinata 3* L: Average rolls 8,8,8,7. Actual rolls 7,8,8,7 slightly below average - not happy about serve if being usedas such.

Ethan Baptiste 4* OH Average rolls 9,9,9,9,9 (not bothered about SET). Actual 8,10,9,9,10 slightly above average - not happy about ATK

Austin Fletcher 5* RS Average rolls 10.5,10.5,12*,9 Actual 10,11,12*,8 (12* guaranteed) slightly below average but 12 ATK helps

Kole Wheeler 5* MB Average rolls 10.5,10.5,11*,6.5  Actual 11,11,11*,7 (11* guaranteed) almost perfect

Overall - above average, nothing spectacular but way better than Quincy, for instance.
