Component or coaxial speakers?

[eflb55]

I've heard that component speakers sound better because the tweeter is not near your feet but is mounted farther up. I can understand that speaker placement will make a difference but how large of a difference is this.

This is what I'm looking at for front speakers in my sedan:
Kicker coaxial $100

Kicker component $200

I really don't want to spend $200 on my front set alone and would like to get the coaxial speakers and I'm just wondering if getting the component is really worth it.
