I believe using distilled water can be harmful. I'd stick with the purified water over the distilled.
"Purified" is a code word for "reverse osmosis" which is another way to purify water.

I think distilled water tends to get a bad rap because it sounds like a chemical process (and is associated with making alcohol). All it really means is that the water has been forced to evaporate and then re-condensed. Morning dew is the exact same thing.
