If you are intent on listening to them both, why don't you get a run of 5e and just try it out without having it installed in the wall? If you like it better, then have it strung properly.
I have used neither for audio purposes, but did just have 15 miles of cat6 installed in our new corporate HQ with some runs well over 300 feet, and not a single cable has had to be replaced or reterminated. The majority of the drops are used for business class workstations, but we do have some server class machines with persistent DB connections where packet loss has to be minimized.
If I was being asked this question specifically for a data network build I would recommend cat6. For audio, your mileage may vary.
