The question is too vague. What are you planning on using the water bottle for? Are you going to be exercising with it and don’t want it to leak? Are you going to be drinking ice cold drinks at a theme park over your lunch break and need help keeping them cold all day long? Will this container primarily live in your house, and will you typically be filling it up with tap water or average convenience store water that’s room temperature or warmer than that? How big of a difference can one type of material make in regards to daily use versus storing said bottle long term just once for pictures for an article like this one. Hopefully these questions help give some clarity!
