There is quite a good technical discussion on this at TDS. Much of it is theory and opinion, but that is where learning starts IMO. I have been a staunch advocate of OEM fluids, but I am seriously considering the ELC coolant when my warranty runs out. Until then, I will frequently check the nitrite levels and flush the coolant every 40k miles (every 2 years). I believe that the flushes and the coolant filter will keep my system healthy. I will say that I was one of the group that found a TON of solids when I first installed the coolant filter. I know that my oil cooler is partially plugged due to the first 15k miles, but I monitor it and it is not too bad.
