The short answer

Pick Phuket from November to April if you want the most choice — beaches, island-hopping to Phi Phi and Phang Nga Bay, cheaper flights and lively nights. Pick Koh Samui from January to September for a more polished, relaxed resort island, and when the Andaman coast is in its rainy season (roughly May–October).

Why not both?

Combining Phuket and Koh Samui in one trip

PhuketKoh Samui
Distance (as the crow flies)
254 km
Getting between them
Flight ≈1 h, or bus + ferry (most of a day)

They sit on different coasts, so combining them costs a travel day. The quickest option is a short domestic flight; the budget option is a bus across the peninsula to Surat Thani/Donsak and a ferry to Samui. It works best in January–April, the only stretch when both coasts are usually in good shape.
