Admittedly I've never looked through an aspheric 36mm so can't really say which is better. I had a TV 2" 40mm WF on my 8"SCT and it gave 50X, not super "low power" but very very nice. In my frac it is 23.8X and definitely low power.
I think you meant the baader 36 72 bigger aFOV than aero40 68, only have owned 40 68 with 2032mm sct. My friend had a 32mm for his, which was wasn't very "low power" but was his low power eyepiece.
I'm not sure if 4 degrees is that much to give or take, but the low power views should be pushed imho. I suppose it also depends on exit pupil demands, glasses and such. For me it worked out great. Next gathering I may hunt down an 8"cat and see what the ES40 68 looks like compared to the old TV40mm WF.
