The trick to this is to get the right features showing and not clutter things up. Here are the settings I use for our area:
=====================================================
In Settings.......
...Enable Geonames POI's
...Distance about 2/3 to 3/4 on slider
...Enable Wikipedia POIs
In Facilities ....
...Enable Facilities Icons
...check using floating icons
...Check Towered airports
...check non-towered airports
In Hydrography.....
...Check show only these features
...Check all but springs and others
In Mountain, Hill, Rock, Sand .....
...Check Mountains
...Check Hills
In City, Village ....
...check major city
...check populated place
In Forest, Heath ....
... Check .. show only these features
... check forest, reservoir, trees
In Spot Building, Farm ....
... Check show only these features
... Dam, ruined dam
(Remember, you already have airports checked so not needed here)
In Underwater ...
...check show only these features
...check show all features
(this will give you underwater reef positions, etc)
===================================================
If you check everything, it will be way too cluttered. It will give you the local historical society building, etc. For our kind of flying, we need more of the geography. Even with these checked, Ketchikan and the larger municipalities are pretty cluttered. What I like is being able to turn it on and off. When I'm approaching an airport, I turn it off, so the green "marker" isn't on the runway, etc. So you use it when you want to. Also the Wikipedia feature is pretty neat. You can learn a lot about an area by using this feature.
