Karthus typically has a much larger longest kill spree than his counter does. Typically, Karthus receives more damage than Yuumi. This typically indicates different amounts of tankyness, but it can also show that the champion with more HP has less agility and thus is unable to kite away from further damage when poked or engaged.

Karthus commonly racks up many more minion kills than Yuumi. Champs that don't earn a lot of minion kills typically don't require much CS to be effective. They are capable of scaling properly off of their skills and stats alone. However, champions with plenty of CS, such as hyper-carries, usually have to have a lot of gold to be effective. In either situation, try to top the values shown here to do well.
