Its hard to find out about the Audio note one's, but they appear to be oil/paper so easily ruled out on lifetime issues, paper oxidizes over time, and absorbs moisture. This means the performance will change over time.
The Audyn one's have a polypropylene dielectric so are low-distortion and aren't going to deteriorate.
But there's no point whatsoever paying money for posh caps, standard polypropylene will do the job at reasonable price. One useful thing is to be able to check the ESR, ESL and self-resonant frequency and loss tangent (ie heat dissipation) in the datasheet, so any caps without a proper datasheet is at best questionable.

The more important characteristic is how the pins are connected to the plates inside but few manufacturers would tell you that because this business is funded by nice stories and esoterics. Besides, I doubt you`d achieve a 1st order with a single cap on a tweeter, unless you cross it at 10Khz or so and it has a very mild impedance peak.
