Our verdict
These attract the same charter flights and completely different travellers. Kos (3.7) is the easy Dodecanese package: flat, cyclable, long sandy beaches (4.0), Hippocrates' Asklepieion for a culture morning, and honest prices (3.8). Santorini (4.8) is the world-famous one — caldera, wine, architecture — at world-famous prices (1.0) and with beaches that are volcanic curiosities rather than swimming destinations (3.2).
The decision is almost financial. A week on Kos costs roughly what three nights on Santorini do, hotel for hotel. If this is the year's one big trip and the caldera photo is the dream, take Santorini and don't look at receipts. If you want two easy weeks of sun with kids or a bike, Kos delivers exactly that — and you can day-trip to Nisyros' volcano for your geological drama at a fraction of the cost.
Verdict: Santorini for the bucket list, Kos for the actual holiday.
