Josh...the old what you can't see can hurt you applies here. The problems develop with in the engine and coolant passages. Because the stuff is so sticky it adheres to things inside. By the time you see indications in the expansion tank, things have gotten really bad. Once the Dex is exposed to air (low coolant levels) it turns quite acidic.
I've been a proponent of the G05 green "all makes/all models" for years, and have used it in all the vehicles I own and service and have been happy with it. As I generally buy used cars, they come with the Dex. It'* the first thing to go!
GM in its quest to make for a "maintenance free" car for what was the usual new car buyer (100k mile plugs, 5 year anti-freeze, etc) went down the wrong path. Ford and Chrysler went with what had been going on in the European markets - the G05 type.
