At this level the differences between eyepieces are pretty minimal and often subjective based on personal preference. In addition, it can often take very good conditions, a very good telescope and a very skilled observer to detect some of these differences. Fitting most of those criteria, the 10mm Pentax has greater eye relief (not a marginal difference), better light transmission, better contrast, and a cooler more neutral colour tone. On the other hand a Nagler has a slightly larger FOV although the 10mm Pentax XW at 70 deg is perfect for most. I have used just about every premium eyepiece thats currently available new or second hand (I own most of em !!) and I rate the 10mm Pentax XW and the 13mm Ethos as the 2 best general purpose eyepieces currently available to the amateur astronomer.
My choices would be (assuming you don't wear glasses)
1) 26mm Nagler T5. It is a clearly better eyepiece than the 24mm Panoptic, in just about every respect. It's also a lot more money.
2) 13mm ETHOS
3) 10mm Pentax XW
Televue 2X Barlow.
