Advice needed: Have 2 Power Cables only need 1 - Which is better?

Yeah I am struggling.  Like them both and will sell the other.  Would rather keep what is perceived as better but it is a tough call!

Listen to each one for a week straight.

I often read that humans have the sonic memory of a Goldfish, but then why can we recognize the sound of a persons voice (not  seen/heard) for decades?

I've never compared power cords.  I just plugged them all in.  I can't say I've ever heard a big difference. 

I don't have any real expensive cables. One by Crystal Clear Audio (Signature silver cable), some by Core Power Technologies, and some by XLO and Audioquest.

I suppose I should try comparing them some day. 

First world problem. Don't waste your time agonizing over insignificant details. You said both sound good. Pick the prettier or cheaper one and sell the other. Spend more time enjoying the music.

How can someone who’s not heard your system or has no idea what you like can tell you which one of the two cables is better. The only person who would know that is you.

And if you ask my opinion I would sell both and buy a kimber pk ascent.
