either over time and practice are about the same, the trick with laptops is knowing how to take them apart. I work with laptops and they can be very tedious and time comsuming to take apart, like replacing a motherboard. but then again replacing a motherboard on a PC is quite time consuming as well.
But laptops do have certain ways they need to be taken apart and different brands of laptops require different methods, a certain order that must be followed.
Perhaps if you are not all that familiar with laptops I would go the PC route, taking a PC apart is probably easier.
