We looked at Zeiss, Leica, and Swarovski zooms. The Leica had the best eye relief throughout the viewing range, but still not enough for my tastes. If zoom eyepieces were the only choice on the planet, I'd pick the Swarovski ATS 80mm ED with the 20-60 zoom. It is a superbly designed birding tool.
We’ve narrowed the choice to:
Nikon Fieldscope 82mm AN ED
30X DS eyepiece
50X DS eyepiece
Swarovski ATS 80mm ED
30X eyepiece
45X eyepiece
Allow me to state a few preferences:
We want a view on the order of the Nikon SE.
Price is not a determining factor.
We’ll need a low and high magnification eyepiece; a zoom is not an option for higher magnification.
Helical focus is preferred.
