Which main power cord?

Cullen Crossover Series vs. Synergistic Research Core AC.

I'm looking for a power cord to feed my power conditioner. All the front end components get plugged into my Furman Elite 15pfi while the power amp goes directly into the wall outlet.
Does anyone have experience with each of these cables? There is not a lot of information on either and they are both comparably priced. Any feedback would be helpful.
