Just to add a bit more to this....
I am currently in Mexico on a vacation and agonized over which binoculars to bring, since I have ended up with so many at the moment. My two "premium" options are the Leica Ultravid 7x42 HD and the Nikon EDG 10x32 that I mentioned above.
After going back and forth endlessly, I ended up bringing the EDG. I was concerned that the 10x32 wouldn't be a good enough "all around" format for different types of birding, but the deciding factors were (1) the reduced size and weight of the 32mm EDG vs the 42mm UVHD and (2) my desire to have extra magnification for open habitats and more distant birds, especially since I wasn't bringing a scope with me.
I've been birding now in various habitats, including open arid high desert, tangled thickets of tropical scrub, and high elevation pine/oak cloud forest, and have not regretted my choice one bit.
Even in the dim, murky lighting of cloud forest at ~10,000' elevation shrouded in mist, the EDG have been perfect and I haven't been bothered by the small exit pupil at all.
As I noted above, adaption is important and I'm sure if I directly compared to the 7x42 UVHD it would feel much "calmer" and "easier", but without that alternate reference point I haven't even thought about the 3.2mm exit pupil. And the extra magnification has proved quite useful in several situations.
Of note, the guide we birded with also used 10x32 (Swaro SV) and he uses them in various habitats all over Mexico.
The one thing I'll say is that with a "challenging" format like 10x32, quality matters a lot more. I'm not sure my impression would be favorable if I was using an inexpensive 10x32. It's a lot easier to make a decent 8x42 because there's more "margin for error" with the forgiving nature of the large exit pupil. So if you're going to go 10x32, be prepared to pony up for something high quality.
(also, on a side note, we swapped binoculars for a few minutes and I very much preferred the EDG to the Swaro SV... the 10x32 SV has much more severe AMD, and the EDG felt more natural without the "rolling ball" spatial distortion when panning and superior color saturation and neutrality.... the EDG are really special binoculars, nearly perfect optically IMO)
