I think it's debateable.

Energy Regen runes get you just over +2 energy per second at level 18, or about a 50% increase in energy regen. It greatly increases your staying power in a fight if you need to be hitting your abilities consistently over time.

Full energy runes give you approximately +40 energy. (20% increase) which is about one more ability than you would have gotten without them. Which is useful if you need to drop everything on them right now.

The debate is because most energy users have an ability that gives some energy back. (Kennen has two.) So does the one more ability that they are able to pull off with a larger energy pool allow them to regenerate faster than if they just get regen runes? It's possible, but you have to drop your combos specifically with regenerating energy in mind.

My personal preference is the regen runes. It gives me a little more flexibility I think while not running into too many problems mid fight.
