James, The very first thing I noticed, is that it does not have the city boundary for Granbury correct [link].
IDK if this will play a factor in what you do, but at the very minimum indicates they may not be as fast as other sources to bring in updates.

Ref: City shape in CityStrides not quite like official or OSM
Note: Granbury was fixed, so the CS link shows correct, not the old, boundary. At the time of this post, the Maptiler show an old/incorrect boundary.
PS. Will continue to scrutinize Maptiler.
