Glass: Probably gets the cleanest and is free from chemicals, but breakable and often heavier to carry.
No matter what choose what feels right to you. Not everything is 100% safe but generally glass or metal could be deemed safer than plastic. Make sure you wash your bottles well and keep the caps off when air drying so no water remains inside that can grow mold. Cheers!
