Nikon Monarch question

[thump]

The eye relief on the new 8x42 Nikon Monarch 5 is 19.6mm and the exit pupil is 5.25 compared to the 8x42 Monarch 3 which has an eye relief of 24.1 and an exit pupil of 5.3 .the 5's are smaller and have the ED glass which would you buy?
Thanks Luke

I think the 5's are better in low light.  Those are the ones I chose.
