I chose 3210 specifically because it has the "old" Garmin interface which I find much clearer, easier to use and more flexible. New interface is aimed at, how shall I put it, people who don't really navigate well, I guess.
NMEA 2000 in my personal opinion is a protocol that is a "solution looking for a problem", and is not useful at all on a sailboat. (That and serial protocols are considerably more resilient in face of marginal connections and variable power conditions often encountered on a boat than Ethernet).
