19mm Pan vs 18mm Radian

I'd like to take advantage of the sale before x-mas and I cannot decide between these two. Is the only difference eye relief/field of view? I am mostly concerned with sharp flat fields and bright/high contrast images, I am leaning towards the Radian. I like mostly bright Messier Objects and planets, as I live in the City. I have a 4"f/10 refractor and an 8" f6 reflector, any help would be appreciated!

I'd go for the pan because of its wider field but either one would be a good choice. I think the 20mm of eye relief on the radian is overkill, unless you wear glasses.

I have the 19mm Pan and 12mm Radian and find them both to be very useful eyepieces. My guess is that you would be happy with either the Pan or the Radian. Personally I would go for the wider FOV of the Panoptic, but then I have always had thoughts about owning a 20mm Nagler.
