The Tele Vue 32mm and 40mm Plossl's and Panoptic 24mm all have a 27mm field stop and therefore all have the same actual field of view in use. They will however show different magnifications and different apparent fields of view. The 32mm has 22mm eye relief and the 40mm has 28mm.

The Hyperion aspheric 31mm is a 2" eyepiece but it comes with a screw on 1.25" barrel that allows it to be used as a 1.25" eyepiece. It's field of view will be less than in 2" mode but is still effectively wider than other 1.25" options. It has 17mm eye relief and a 30mm field stop in 1.25 inch mode. I've not had an opportunity to try one.
