Overflow options

New to this and setting up a 40 gallon tank. Would like opinions on overflow options. Should I setup to skim from the surface or pull the water from deeper in the tank? I do plan on a couple of wavemaker pumps, if that helps
 
Need more info. You are using a sump or a canister filter? I ask because overflows have to draw from the surface, only a syphon tube can draw from below.
