Without necessarily intending to, you're showing that the MRA app and a Garmin GPS respectively focus on different things. You're correct that a Garmin doesn't capture images, texts and colors. If that's your main focus, then the app is a good choice. For me personally, all this falls into the category of up-front planning, so I don't find it to be priority #1.
On the other hand, a Gamin excels at core navigation capabilities. The units (depending on model) dynamically capture 20+ trip data metrics in the areas of navigation and route data. They're all available for viewing (as they're updated) during the ride. Most of these elements are simply not captured in the MRA app. Also important, a Garmin GPS provides more detailed and vibrant 3D navigation maps (especially the XT3), has superior off-route navigation capabilities, the ability search "up ahead" in a number of categories, and if you choose to, dynamically modify your route for additional unplanned stops. This all falls into the category of core capabilities, which for me is my focus while on the road.
So "better" is going to depend on what's most important to an individual rider. There really isn't an absolute when considering the choices.
