I'm just now jumping in, as I received my NL 8x32, but I have been following this and related discussions.
I purchased the NL32 to replace my EL32 (and hand those off to my wife), because I'm tired of my little finger not quite fitting between the two bridges without a squeeze, and knowing that in winter that finder will again be pointed skyward like I'm at a tea party... Otherwise I love the EL32, so criticism of the NL32 on the grounds that it didn't change much optically haven't discouraged me.
My first impression is disappointment because of the shape, especially since I was expecting to like the narrowed grip as a safe replacement for the thumb indent. The thumb indent on the EL32 fits my hand perfectly, totally love it, but the indent on the EL42 is off for me and I really dislike it. So, seeing the waisted appearance of the NLs made me think that swarovski found a new way to ensure that the NLs feel nice in anyone's hands. Not so. I have seen no picture that accurately reflects how the NL32 is shaped. Someone described it as a smashed beer can, and that's right on, right down to the uneven, uncomfortably acute bends at the edges. Another image that came to my mind is a smashed hoagie sandwich - it's flatter in the hand than I expected and there is a prominent ridge from the focuser toward the objective end that I did not understand from pictures.
On the plus side, I found that I can fit my little finger on the barrel now, with or without gloves, and I like that I can even wrap fingers from both hands around the barrels at the same time(without gloves). These are big ergonomic wins for me, as I found that the ability to grasp the Zeiss HT42 with both hands made me want to use those more than my EL42, even though I prefer the view through the EL42. And, with gloves, I found that the, honestly, super weird cross section of the barrels was less unnerving. The focuser is wonderful, though I haven't had a chance to see whether it is too slow for my preferred use (I think it's the same as the EL32, which is a bit on the slow side for me). I was also relieved to find that I don't notice a change in overall size or weight from the EL32, seems like a direct replacement in the category in this regard, and I am happy that I looked away from the specs sheet on this point.
I don't have the expertise or experience to comment on the comparative optics, and others have thought about this and write about it better anyway. I will give this ergonomics situation a think and will take them out a time or two so I can give my hands' apparent disdain for the unfamiliar a chance to simmer down before I make any decisions. It is a shame, though, that this isn't the home run that I was hoping for, at least at first blush.
