Green vs black tea, at a glance

Question	The answer
Is green "better"?	No; both are the same plant, the difference is processing and taste, not a winner
Health	Both have a modest, similar, much-overstated antioxidant story; neither is a cure
Caffeine	Black usually higher, green lower; brew and type vary it more than colour
Real difference	Flavour and ritual: fresh/vegetal vs brisk/malty
Bottom line	"Both is fine", choose by taste and moment, not a league table

Why people think green wins, and the real differences

The belief that green tea is "better" than black is a textbook tea myth, and seeing where it comes from is most of dismantling it. It rests on a health halo: green has been marketed for decades around antioxidants and "detox", so people assume black must be inferior, when both are leaves of the same plant, Camellia sinensis, and the difference is entirely processing, green is fixed with heat to halt oxidation, black is fully oxidised, see oxidation explained. The health stories are modest, broadly similar and equally overstated for both; neither is a cure, a detox or a weight-loss agent, and the real, defensible benefits, a near-zero-calorie pleasant ritual and a calm caffeine lift, apply to both. The genuine differences are flavour and caffeine: green is fresher, more vegetal and brew-sensitive, while black is brisker, maltier and milk-friendly; black is usually higher in caffeine and green lower, but type and brewing move that more than the colour does, so a strong gunpowder green can out-caffeinate a delicate black.

How to judge any "which tea is better" claim

"Green beats black" is one instance of a recurring shape, a real, narrow fact inflated by marketing into a confident ranking, so it is worth the filter that defuses the whole category. Ask three things. Is it the same plant or different: green and black are the same species, so any "better" claim has to be about processing, not the plant. Is the effect large or trivial: the health signals (modest cardiovascular and metabolic associations, the caffeine-plus-theanine lift) are small and similar for both, so they cannot rank one above the other. And what is the hidden variable: here it is taste preference and a marketing halo, neither of which is a health fact. Run it through and the "winner" dissolves. What actually matters when choosing is practical: fresh and light or robust and milky; a morning lift or an all-day cup; with milk (which suits black and ruins delicate green) or without; and which you enjoy enough to drink regularly, because the tea you keep drinking beats the "better" one you abandon.
