The best water IMO is warm purified/filtered bottled water. It has about 1/3 the chemicals as tap water and is not acidic like high end RO water. I know a lot of bottled water says it is RO water but it is low end RO water.
I grow hydroponic produce for a living so I have learned a lot about water quality in the last few years. With out getting technical the average gallon of tap water has about 1 teaspoon of chemicals in it. I know that does not sound like much but 1 1/2 teaspoons of fertilizer per gallon of water gives it all the nutrients vegetables need to grow hydroponically.
