I haven't used both these apis. But from what I see, GeoAPI seems to provide writable layers if you would want to augment their data with your own data which would be available just to you, while simplegeo doesn't provide it yet. On the other hand, Sinplegeo seems to give an API that enables you to query for predicted population density in an area. Simplegeo seems to provide history for the users or objects that you are tracking while geoapi doesn't seem to provide. See which of these features matter to you and which don't. These are from what I understood by going through the docs in a few mins just for answering this question since geo is one of my interests. So, I may have overlooked something. Please verify these yourself once.

CEO of SimpleGeo here to clear some things up:

SimpleGeo does provide "writeable layers". This is our primary feature. Essentially, developers can create a private layer, then start populating that layer with points. Those points can be checkins, media, breadcrumbs, points of interest...anything, really.

The SpotRank data (provided by Skyhook) is an additional API endpoint that allows you to see the current population density of a given area based on cell phone usage.

We do provide breadcrumbing, or user history if you will. This pairs nicely with iPhone OS 4.0's new background location.

Beyond all of this, we're turning on our Marketplace shortly. We've gone out and found lots of great geodata to expose to developers. Some developers have also begun to contribute their own geodata to the Marketplace.

Hope this helps! (We do need some better messaging on our website for sure).
