The UG is much more usable for a beginner, and for the vast majority of people who aren't into programming xgauges. Instead of tedious SG programming while guessing which OBD-II communications protocol your car uses, you plug the UG in, and it recognizes the protocol within seconds, and displays the available standard gauges that most of us use.

Bottom line: if I were to buy one tomorrow, for myself or as a gift, I'd buy another UG. It's less than half the price of the SG, looks better (much more modern display), and displays six parameters per screen, with three screens available. The SG shows only four parameters. With the UG, if I want to display g/h, distance to empty, and avg tank mpg, and they're not on my main screen, one push of a button and they're all on my second screen. With the SG, I have to cycle through the dozen or so standard gauges and 24 xgauges each time I want to change just one of the four displayed parameters. That's 20 or so button pushes to get to g/h, and another 20 or so to get to DTE - tedious stuff.

I have both also and could not have written a better assessment...
