I have used a Wash atlas & gaz for years and it is a great book in my opinion. I use it for hunting, fishing new lakes, camping in a new area, snowmobiling etc. I like the detail and it has a lot of great info. If I'm going to a new lake it shows you where the boat launches are , campgrounds etc. I use mine so much I have to get a new one about every five years, I end up taking pages out for a last minute snowmobile ride or hike in new area. No experience with the other book, this one is well worth the money. Mike
