No need for it to get nasty. Both areas fit the needs of different folks. SD is hot right now (we've all seen/heard about the perch) with multi-species opportunities. IGL is more less consistent now but still can have great bites and allows for great sight fishing (spots on West are gin clear now). If I lived in the middle of both, I'd probably hit up SD more but since I live in Spirit Lake, convenience is a big factor for me. All depends what a person is looking for but both can be great destinations.
