TeaHQ has written about this pair

Chai is a preparation, not a tea. Understanding that resolves most of the confusion about why the leaf sold for it tastes harsh on its own.

What it is
Chai blend base: Small-particle CTC Assam, manufactured to extract fast and hard.Assam: Orthodox or CTC Assam sold to be drunk as tea.
How it is prepared
Chai blend base: Simmered with water, milk, sugar and spice, brought to the boil more than once.Assam: Steeped in hot water for a few minutes.
Why the leaf is cut so small
Chai blend base: It must stay visible through milk, sugar and spice, which whole leaf does not do.Assam: Leaf size is chosen for the character wanted in the cup.
Drunk plain
Chai blend base: Harsh and tannic, and not intended to be.Assam: Fine, with or without milk.
Is it a lesser tea
Chai blend base: No. It is engineered for a job that whole leaf does badly.Assam: No.

In summary: Judge the chai base by the chai, not by a plain cup. It is one of the clearest cases in tea of a product being designed for a preparation rather than for itself.

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.
