RealSimGear vs. FlightSimBuilder GNS 530

Hi. I am thinking about getting a GNS 530 for MSFS 2020 and have been looking at RealSimGear. I have also seen FlightSimBuilders version which is about $150 cheaper than the the RealSimGear.

Has anyone seen a comparison of each or have an opinion on which one to get.

I am leaning towards RSG since it has been around a while and is supported in Spad.Next.

Any suggestions will be welcomed.

I have the RSG G1000 suite (not the 530 but still RSG hardware) and those folks have been super helpful last year when I first setup. They’ve been great with questions and support of new aircraft when needed for the popouts. Nothing bad to say about RSG, their hardware and support have been great.

Not to mention, the 530 hardware will work in both MSFS and XP if needed. Not sure about the FSB hardware
