Honestly when it comes to fighting the big guys, the difference is negligible. It's just that it's easy to kill little things like minions and mini monsters with.

The main investment with armor penetration runes is that it mitigates the effectiveness of enemies' even further causing the mid game and late game to become much more powerful. It really boils down to how good you are at farming. If you can't even farm, then is just required because it's harder to farm with armor pen.
