I understand the advantage of a larger exit pupil for the 42mm lens in low light, but in the same brand model and coatings, what else does the 42mm lens offer over the 32mm? Thanks.

Nothing, really. Assuming all else is equal.
Some people say that a 42mm would allow them to resolve details better, or offer a more pleasant view. However, that is a matter of perception and preferences and a person's eyes The advantage of 42mm at dusk and in low light is minimal, just a few minutes. I prefer 32 mm because of size, weight, and feel in the hand. |

And for a very long time, 8x32s had 10% more field of view and 8-12 oz. less weight. Even with the latest generation of ultra premium models, the difference in weight is still there. |

The 8 x 42 is felt by many to be a good all around useful set. If you are going on a cruise the waterproof versions would be perfect. 8 x 32 or 7 x 35 are also good basic sets for all around viewing. When you get bigger on the magnification (first number) or too large on the second (light gathering capacity) you get into weight considerations, and the ability to keep them steady for very long. I have a tripod for my 10 x 50's when I go bird watching from somewhat longer distances which makes viewing much more enjoyable.

8x42, as previoiusly mentioned, will give you a bit more performance in low light. The other difference is weight, which can go both ways. Heavier 8x42 is harder to carry, but it is more stable to hold. Choose what is more important for you. If I am doing prolonged glassing, I go larger. It cuts down on eye fatigue. If the glassing session is not too long, I go smaller.
