Taliyah usually has a much larger longest kill spree than her opponent does. Typically, she receives more damage than Nami. This is usually reflective of different amounts of tankyness, yet it can also indicate that the champion with more health has less mobility and thus is not able to flee from additional damage when engaged or poked.

While Taliyah does have a lower win rate than Nami, when they face off with one another, Taliyah also has a greater difficulty level that makes her a more time consuming character to pick up and master. You should be careful when picking Taliyah into Nami.
