I'm not sure I did a great job of capturing the differences, but after playing both back to back I stand by my original statement that the Naupaka sounds slightly better.
Here is a link to some sound samples of the two tenors.

Please excuse the inconsistencies in my playing and the volume. On the latter, I forgot that I had recently deleted Audacity and had to use the Win10 recorder that didn't seem to allow for easy control of the mic volume.
To avoid bias, I labeled the samples Tenor 1 and Tenor 2. I tried to put which tenor is which in white font at the bottom of this post but it got marked as spam. I'll update the post with the answer key tomorrow.
