Black coffee and tea are considered the healthiest options because no sugar, no sugar substitutes, no preservatives or other additives, and they’ve been used long enough that the health implications are well researched.
Diet sodas have ingredients that are considered safe in moderation by the FDA, but we are still learning about the long term effects of artificial sugars and different additives. There are caffeinated seltzers out there with just natural flavoring and caffeine. That would probably be a better comparison to black coffee and tea.
