I found this post: https://gist.github.com/Jeff-Russ/2105d1a9e97a099ca1509de1392cd314 which indicates switch/case to be faster than if/elseif with ===.

They also indicate nested if statements which makes a lot more sense and also provide far better results.

Their times:

nested if/elseif === : 0.25623297691345 (NESTED IF)

switch/case : 0.33157801628113 (SWITCH CASE)

if/elseif with === : 0.45587396621704 (FLAT IF)

only if with === : 0.45587396621704 (ONLY IF)
