That's what I liked with the Raymarine. It looks very intuitive and you can drag and drop different screens ( sounder, plotter etc..) to have a variety of split screens with what you want on it. Like a smart phone you can swipe left, right etc... to bring up different functions.
I have a Garmin too Gimp but with the buttons on it you have to go through multiple screens to get to what you want.
