Default Serious coolant Questions

Ok reading the 402 thread made me think of something. What should be used for coolant? I have read and searched and it seems mostly opinion based and a he said she said deal.

I would like this thread to be based on hard facts. Everyone says dexcool is horrible yet thats whats in the cars and trucks, as far as I know. I guess I would like to know why dexcool is so bad or good? what other options do we have? whats the good and bad about those? And last if we change to something else, what kinda of flushing do we need to do? I guess this really isn't an LS1 but more of a general maintenance question, but of course more toward our cars.

I would prefer this to be a no opinion thread and based on facts and actual sites that someone could go to?

I just changed my buddies coolant in a 93 caddy and the overflow was crusty and just plain nasty. Ran some pure water in it and put in what ever he bought and she ran fine. Now I would like to do it to mine here in a few weeks but don't want to just throw anything in the ole ta and want to learn more about the system and engine!

Thanks in advice
