I went with Raymarine when I got a chart plotter and upgraded our radar since we already had Raymarine AP and instruments. If I had it to do over again I would go with Garmin. The integration aspect was over-rated, especially since I added a PC with Coastal Explorer and a Miltech AIS. My older AP won't talk to my Chartplotter anyway in spite of what Raymarine told be beforehand. Garmin's Human Machine Interface (HMI in industrial controls parlance) beats Raymarine hands down.
