I recently did an extended at home comparison between SF and NL, both in 10x32.
After six days of really wanting to love the NL, I could not get what felt like a natural and comfortable hold on the pinched-waist NV barrels. And, the armor on the NL felt just a little slippery compared to the better stiction of the SF armor. The handling of the 10x32 NL was a problem for me, personally.
The traditional barrel shape of the SF dropped into my hands with an immediately natural-feeling, comfortable hold. And the stiction of the SF armor felt much more secure in my hands.
The optics of the NL were very good, as they are with the SF; it was the feel in the hands/handling of the NL that I could not get comfortable with, after six days of trying to do so. I sent the NL back and was relieved to have made a decisive choice.
Though my comparison did not include the Noctivid, I'm sharing this with you to point out that the feel in the hands/handling is just as important as optics, view, etc.
So, don't be too hasty to switch to NL; make sure that you love how they feel in your hands before jumping ship. And, make sure you love the view even more than you do with the Noctivid.
Any other individual's preference may very well not apply to you. So, as others have advised you, above, you have to personally test them out for yourself before you can know what feels just right to you.
I haven't tried a Noctivid, but I am quite familiar with Leica UVHD+, and I will say that the Leica "view" (color quality, contrast) is definitely, absolutely quite delicious! My hunch is that the color quality and contrast with the Noctivid is likely fantastic.
