Welcome!
It it really depends on the big picture. You need to provide more details of your build (frame, ESCs etc) for people to give you a good suggestion. It also depends on what you plan to do with it - aerial photo/video will surely require more lift-payload capability, which would help determine your needs for the motor.
Also, don't be afraid to head over to eCalc and plug in some numbers. It definitely helps show you the ballpark performance of what different options provide.
