Short answer: neither is “better” overall—it depends on what you like.

Key differences (typical 12 oz can, US formulas):
- Taste: Pepsi is sweeter with a slight citrus note; Coca‑Cola is a bit sharper with more vanilla/caramel and higher acidity.
- Sweetness/calories: Pepsi ~41 g sugar, ~150 kcal; Coke ~39 g sugar, ~140 kcal.
- Caffeine: Pepsi ~38 mg; Coke ~34 mg.
- Sodium: Coke ~45 mg; Pepsi ~30 mg.
- Mouthfeel: Many find Coke “crisper,” Pepsi “smoother/sweeter.”

Recommendations by preference:
- If you like sweeter, fruitier first sips: Pepsi.
- If you prefer a drier, more “spicy/vanilla-caramel” profile that pairs well with food: Coca‑Cola.
- Watching sugar/caffeine: both are high; consider diet/zero versions (their taste differences persist but are smaller).

Notes:
- “Cola” can mean any cola; most people mean Coca‑Cola.
- Cane sugar versions (e.g., “Mexican Coke,” “Pepsi Throwback”) taste a bit cleaner vs high-fructose corn syrup.
- Blind “sip tests” often favor Pepsi; over a whole can, some prefer Coke’s lower sweetness.

If you tell me what flavors you enjoy (sweeter vs crisper, with food vs solo), I can give a more specific pick.
