The advantage to the green coolant is it doesn't turn into Jello in the radiator/heater core.
My Dex-Cruel turned to Jello early, ruining the heater core and plugging the radiator enough to cause overheating. GM/ Dealer said that is caused by "Contamination". They said ANYTHING could be a contaminant including air.
