Just a note, the UG and SCII both show all the regular OBD2 info, but the SCII can be programmed with x-gauges to show more. How much more depends on the car. Some (most?) don't have any extra gauges, some have a couple like transmission temperature or EGT, while hybrids have a whole list of extras (battery SOC, amps, motor temps, etc).
For most regular gas cars, I would recommend the UG over the SCII because it's cheaper, has a bigger and (in my opinion) better screen, and can show pretty much everything the average car is capable of showing. Heck, I even use a UG in my Prius (I have a cable for my laptop that I can use to check the hybrid stuff if needed). If you have a car that has x-gauges available that matter to you, then the SCII can make a lot of sense. Their customer service is also top notch (never had to deal with UG's). I've never used a SGe.
