I live in Wisconsin and have hunted all over the state, most of the hunting I do is on public land. The best public land opertunitys come in South central, South Western, and West Central Wisconsin in the hilly areas. I also do real well near my home In S.E. Wisconsin, but thats not hilly, and I do well mostly in large swamps and cattail marshes.
If you don't have private ground, I would recommend staying away from Buffalo county. What little public there is in that county really gets pounded cause of the reputation.
Richland county, sauk, Dane, and others in those areas have done real well for me...
I look at all the public land and look at nearby towns for comparison. I search out the public propertys that are the longest drive from towns and citys. A lot of the time smaller propertys are completly over looked.
