Speaker system comparrison

[BLUCanadian]

hey guys...
just bought my first receiver and pair of floor speakers
But I have recently seen a deal for a package of speakers that has me second guessing my original purchase

I bought the pioneer 1018 receiver and Energy C-500 floor speakers.
I will be looking to complete the Energy 5.1 system with the C-C100, C-R100s, and a sub (not sure if Ill go with Energy)
Total price for the speaker system will be ~$900

I recently found a Klipsch speakers system going for $800
It includes F2 towers, C2 center, S2 surrounds, Sub-10 sub.

My questions
Which system would likely be better?
If the energy system is superior, is it worth the extra $100?
Any other comments/suggestions would be appreciated!
Thanks

There is also a Klipsch Icon system for $950
Includes VF-36s, VS-14s, VC-25, and sub-10
