While Karthus does have a much lower win rate than Fizz, when they face off with one another, Karthus also has a greater difficulty level that makes him a more challenging champ to develop with.

Moreover, Karthus has some amount of CC and other utility, a similar amount to Fizz. This makes her just as valuable during team fights, especially when fighting champions with a ton of burst damage.
