if all else is equal then more edge should be preferred biologically speaking. But other factors are more important in my opinion. More edge doesn't lead to easier hunting, growing, or planting.

Aspect, soil type and depth, and light (how much you want depending on your soil moisture/aspect) should be top of the list.

however, location on property is really important. I've got a 400 acre piece that has about 10 acres in foodplots. the problem is they are all on the south end of the property-by the gates. With a south wind it is next to impossible to sneak in. plus if a person wants to hunt other areas you've got to scare every thing off to get there. So, it really limits morning hunting to a few stands...or you just say the hell with it and drive through.
