I've done both. Still get condensation.

Thing is, if you look at the trunk and the rubber seal, there's a reason why there's a weather seal around the top of the area of the top of the coolant tank, oil dip stick and fill tube. My guess is to keep the hotter temps and humidity (condensation) out of the rest of the trunk. If there was never condensation, there'd be no reason to isolate that area from the rest of the trunk.

I'd have to disagree a bit. The trunk is common to the passenger compartment by way of the clamshell area (vents just above the trunk light). Therefore I believe it is designed to keep hydrocarbons (oil fill) and coolant vapors from potentially entering the passenger compartment and overcoming the occupants. So with top up, positive ventilation is from cowl intake, passenger compartment/ clamshell, trunk and out the flapper vent at the right rear of the trunk.


Edit: This is also why IMHO it is a bad idea to mount any Turbos, accusumps and the like in the trunk.
