That's like asking what's better, hotdogs or hamburgers.
They are different.
It's possible you can get by OK with just blowing out.
It's possible some water will gather in a low spot
and freeze after you do that.
Some folks get by year after year just blowing out.
We can't guess how much pressure or air volume you
can blow thru your system.
Pumping RV antifreeze entirely thru your system is
just about guaranteed to prevent freeze problems.
As far as damage you have already I'm not sure
what you are asking.
Around my house it's way late to be winterizing.
It had better be done by now!!
