Sit-on-top vs sit-in kayaks

[jfishingfiles]

I plan on buying a kayak for fishing and have only looked at sit-in kayaks to purchase. I figure I can put more gear in a sit-in kayak and it can be better protected from water. Recently I spoke with a friend who recommended a sit-on-top kayak and he explained if you flip over it is easier to get back on your kayak and keep kayaking. He said in a sit-in kayak if you flip you have to swim your kayak back to shore because it is hard to get the water out. I just wanted to see what people on here liked best for fishing and why? Sit-on-top or sit-in kayaks? Thanks!
