Lol. Comparing UK to KM is like apples and pears. Two entirely different play styles. UK is KM's weakness, it's countered by US in all tiers apart from BB3. IJN and MN sit in the middle, MN has a slight edge over IJN after the patch. SN is still broken.
Nebraska > QV > Kaiser = Nebraska on one loop
Charle can deal with all BB6 but has a hitbox weakness, only good for rushing
P24 is the defensive BB6, worst for 1v1 situation but good in line fight, opposing style to Charle
Kaiser/Nebraska > Amagi > QV > Kaiser on 2nd loop
