The biggest benefit for having a larger lens at the eye is that it is much easier to find in the dark! The lens of a Plossl from about 10mm or shorter gets pretty small and can be hard to find in the dark, whereas the lens in all of my Pentaxs are the same size...from 40mm down to 5mm, which are much easier to line up with your eye. Most wide angle designs tend to have the same size eye lens.
