Where To Go: Phuket or Koh Samui?
Karon Beach in Phuket.
Both islands are great so this is not a choice with a clear answer or definite recommendation.
One of the biggest factors in your decision will be the weather and what time of year you’re visiting.
I go into month by month variations below but in general the weather on Phuket is better from November until January. The weather is better on Koh Samui from May until September. The weather is very good in both locations from February to April. The weather is awful on both islands in October – when a visit to Koh Samet or Hua Hin would be a better choice.
If you only plan to visit one island or have one week or less then I recommend Koh Samui. It has a more Thai feel, better handles the crowds (busy without feeling overwhelmed or insanely touristy), and has consistently better food.
If you have more than 10 days to spend in south Thailand and are open to the idea of seeing another island then split your time between Koh Samui and Phuket. There are more than 6 direct flights per day between Phuket and Koh Samui and the flight lasts about 55 minutes. If you book far enough in advance fares are very cheap.
Koh Samui has some of the best beaches in Thailand.
