They each have their place.

The Ethos is the thing for getting in a little tighter, to close-in objects.
I am only speaking from experience with the LX-200 though, not a giant dobsession...

The 41mm Panoptic has only 68deg AFOV. However it is an excellent choice for an f10, LX200 giving 4.1mm exit pupil.
Also the 46mm field stop diameter of the 41P is considerably larger than the 36.2mm field stop diameter of the 21E giving a noticeably larger true field. The 31mm Nagler with 82deg AFOV falls in between with a 42mm field stop diameter and 3.1mm exit pupil (f10).
