Quick note on how “best” is measured

• “Best” can mean highest revenue (company scale), highest brand value, or highest consumer popularity — the lists above mix those perspectives and cite market/brand reports and consumer‑survey/social data. Statista and trade rankings show the largest companies by sales; Brand/YouGov/consumer studies show most‑recognized/popular brands. (statista.com, internationalsupermarketnews.com)

If you want, I can:

• Narrow this to one snack category (chips, cookies, chocolate, healthy snacks), or
• Give a ranked “Top 10” by global sales, brand value, or consumer popularity with sources and numbers.
