I'm familiar one particular difference in the area of ADSB.
If you're running Foreflight on an ipad, Dynon doesn't currently pass FIS-B/TIS-B data from its ADSB-470 or ADSB-472 receiver to Foreflight on your tablet. It was a promised feature in 2018 that hasn't yet materialized. So to see this data on both, two separate ADSB receiver devices are needed.
