The 730N has a Harmon NAV system (Tom Tom like). The 430N has a Garmin NAV system. It is really personal preference because neither is really all that better than the other.
The 730N can do split screen, displaying two things like Map and Turn-by-turn directions at the same time. However, Turn-by-turn directions can also be displayed on the EVIC so that might not be all that important.
The 730N can do "dead reckoning" which means it can continue to navigate with the loss of GPS signal (tunnels, urban canyons, etc).
The 730N can do "bread crumbs", recording your off-road trip and then guiding you back along the same route.
The 730N can do "traffic", but you have to pay for that after the free trail period is over. Though, since you are "TrafficGuy", maybe that is really important to you?
Both the 730N and 430N can only use "real" map loads (forgetting about "iffy" hacking of maps on the 430N). Even though the 430N is Garmin based, it doesn't have the standard Garmin micro-SD card slot. So you can't just buy a $30 TOPO map load on a micro-SD card and slap it in.
For just my opinion, I got the 730N, but now feel I should have gotten the 430N. Everything else I use is Garmin based, and because of that, I think I would have enjoyed the 430N more.
