My husband prefers the Duncan Press (green) map to the Bizer map because he feels it is easier to read. I think the green one looks prettier too.
As you can see, we have both. It has been great having the two maps. Another person can learn along side the skipper and I find it nice when we have guests, we aren’t playing pass the map. Another issue for you might be where the map is folded, as each company has a different layout. Does a key location for you fall on the fold? That could make you crazy. Both maps will get you where you are going, so either way you will be fine. I think it will come down to personal preference. You can always do what we did and buy both! Supporting local businesses/sponsors to this site is a good thing. Here is a small sample to see how they differ. Good luck.
