Koh Samui is the clearer pick — 74 vs 57 on the Atlas Ranger Score, our 0–100 measure of weather, crowds, value, and timing across the year. It leads most of the year, though the month-by-month chart still shows the other's stronger windows.
Koh Samui averages a higher weather score (70 vs 52). Weather is the biggest input to the score, but both have strong months and weak months; the month-by-month chart shows exactly when.
Koh Samui has more shoulder- and low-season months, which is where the best value and the fewest crowds are. Travelling outside each destination's peak months is the single biggest way to cut costs.
