Both of those are on sale at Cabela’s/ Bass Pro. I bought the Garmin yesterday and used it today. Lifelong Lowrance user but just had to try the Garmin for my small boat. The Garmin has lakeview HD maps built in and are pretty good. It will also draw contour lines on base maps. It will accept the Uber expensive Panoptix. Imagining is not as good as a Lowrance but good enough. Very intuitive touch screen that works well. Waypoint management very good also. If you can go look at them and push buttons.
