Ekko or Fizz?

Well Ekko is a better champion Aoe Damage and Slow Strong passive Aoe slow or stun Aoe damage from his Ult good mobility on ult and E

Fizz on the other hand , has more damage than Ekko but he becomes really frustrating to play whenever enemies group so you can't ult your target also Fizz early can be easily poked , you need to sacrifice a lot of farm if you don't know how to deal with other picks

Lemme tell ya. Fizz is really easily poked. But, if you get too close, this little guy can destroy you. The same is with Ekko, but personally Fizz is way better. But eh, that's your choice now?

ekko has great teamfight on his W also a threating ultimate finally he can soak up a obscene amount of damage before ulting then its full hp again now you teams can fight while they have no ults up. with also your W as a powerful stun/slow.

fizz is more team capturing/locking the priority target with ult then proceed to finish adc (if able). i personally play fizz more.

ekko is 2x better

Elko can also jg( not the best, but it works) if you get filled it and need ap
