distillation poll

i want to know what kind of water everyone drinks and why. try to keep it small and if you can a couple links.

im stuck i dont know where to get water from. i heard both are the 'best'. im leaning towards distilled water but im looking for some relly convincing evidence. if some one even mentions tap i will hearl. every could benafit from the thread so lets try to make it as informative as possable with out reading for years on the subject. thanks
