Always choose glass if possible!!!

It just has a nicer feel and looks more substantial.

I’ve found no evidence of any taste difference between glass and plastic, but I keep looking. If you want to drink the still water from an ugly plastic bottle in an epicurean context, decant it or put the bottle into a sleeve.

For high-end bottled waters, the glass bottle is a must. The bottles—though sometimes over designed and under functional, as in the case of Voss (the water’s slim bottle is easily jostled)—are the most visible aspect of a water brand. While some bottlers only put their water in glass, other brands establish a distinct identity in both glass and plastic (Ty Nant, for example). Lately, some bottlers that have previously only bottled in PET are moving to glass in order to capture a higher market segment through sales in restaurants and hotels. Perrier, on the other hand, departed in 2001 from its well-known glass bottle by introducing a half-liter PET bottle.

When you see the number 1 in the recycling arrows on the bottom of a drink bottle or jar of peanut butter, that package has been made with polyethylene terephthalate, or PET. This type of polyester is a strong, transparent plastic resin that keeps its shape even when subjected to temperature changes. PET is also fairly cheap to produce, doesn’t shatter like glass, and is lightweight and recyclable.
