| "In tube" filters every time for me. At a push use the type that cover the inlets into the airbox on the tube side.
Anything that goes inside the airbox reduces its volume or reduces the positive effects of the airbox size/shape.
If you're a regular gravel trap visitor It might make sense to use a filter over the trumpets/in the airbox to stop gravel getting in to the inlets when you knock the tank off!!
You might get some of the loses from an undetank setup back with a dyno session/ FIM CHIP or PCIII but in my expererience you won't get the throttle response you get with in tube filters.
