This is largely a matter of personal preference, but here are some general points:

**Pepsi** tends to be slightly sweeter with a citrusy note, which often wins in sip tests.

**Coca-Cola** has a more complex flavor with vanilla and spice notes, and many prefer it with meals or over a full drink.

Blind taste tests have shown mixed results—Pepsi often wins quick sips, while Coke tends to win when people drink more.

Is there a specific context you're choosing between them, like for a party or personal enjoyment? That might help narrow it down.
