Whether an alternative is "better" than Waterdrop depends entirely on your personal hydration goals. Alternatives include plain tap or filtered water (the most cost-effective and natural option), electrolyte powders like Liquid I.V. or Nuun (favored for heavy athletic exertion), or homemade fruit infusions. Waterdrop stands out for portability and zero-sugar flavor variety, but others may prefer different nutrient profiles or price points.
