alot of people seem to like 25 yards as this is at the top of their trajectory, also you then only ever have holdover to worry about.
Alot of top shots seem to like 35 yards, I however preffer 40 yards, I have a half milldot scope and this means all the 15mm apart from 13 and 14 yards are the hall mill dot ablove the cross and 45 is the half milldott below.
Hope thats helps
