I prefer the antifreeze method as it takes care of low spots at can't clear and if water or condensation does form and drain to low spots, there is antifreeze there already. If air pockets can form in many engines after changing coolant, I would be worried pockets of water could remain just by blowing out a system.
For some systems I'd you know what you are doing, blowing them out first eliminates a lot of required antifreeze...but I still like to use it in case of low spots or condensation.
