Actually, speaking from personal experience, the Garmin 24K maps have lots of errors when their birdseye imagery is overlayed vs the topo maps that are found here on GPSfiledepot.com. I have included a couple of screenshots to illustrate this point. I am using the 100K from Garmin because my 24K data was accidentally destroyed, but the alignment issue was the same on both Garmin versions. However, I have not found any errors on maps downloaded from here. The sample I took was random, but the errors from Garmin can be found on pretty much every square inch of their maps, they are terrible in my opinion.
