Neither worked well for me in CO.
Mapsonus gave less detail, even with "more detail" selected.
Map24 gave more detail, but still didn't show parks, etc. However it did allow setting mph to 10-15 mph range to give you a ball park os commute times.
Both failed to show bikeway underpass under highway and to show the parks in industrial park. One of the parks is terminus of bikeway underpass.
