SOTs "sit-on-top" offer more freedom of movement for your lower body. Many kayak anglers prefer SOTs because you can dangle your feet in the water, shift sideways, and sit cross legged. Some are even stable enough you can stand up in them. With a SOT you don't need to worry about getting trapped inside should you tip because you're on top of the boat. You'll simply fall off the kayak, which is a welcome trait to some who find SINKs uncomfortable. Some beginners also find it easier to get on and off of a SOT model.
SINKs "Sit-inside" provide more protection from the elements. Because you sit in these models, the lower half of your body is protected from the sun and the rain, unlike in a SOT. You can purchase spray skirts to prevent water from entering the inside of the kayak. The major advantage to SINKs is you stay drier when kayaking, which is critical in cool climates and foul weather.
