Black tea

TeaHQ has written about this pair

Two assamica blacks that supply most of the world’s teabags, from opposite hemispheres and opposite growing conditions. Between them they account for a large share of what ends up in a teabag.

Climate
Kenyan black tea: Equatorial highland at 1,800–2,200 m, cropping year-round with no dormancy.Assam: A hot low river plain with a monsoon season and a dormant winter.
Consistency
Kenyan black tea: Very high. No dormant season means little variation through the year.Assam: Seasonal — first and second flush differ markedly.
Flavour
Kenyan black tea: Brisk, bright and coloury, with less aromatic complexity.Assam: Malt, raisin and cocoa, with real depth.
What blenders want from it
Kenyan black tea: Colour, briskness and reliability.Assam: Body and malt.
Sold under its own name
Kenyan black tea: Rarely — most disappears into blends.Assam: Frequently.

In summary: Kenya’s advantage is consistency and Assam’s is depth. A breakfast blend usually wants both.

Nothing above is a recommendation. The last row describes the drinker each tea suits, using each tea’s own authored fields and the same sentence structure for both, so neither can be framed as the safe choice.
