The difference I perceived is noticeable at high RPM where the G80 feels like it ramps down engine torque prior to and after the shift to save the gearbox. The DCT has no torque ramp at the shift so it feels faster and more dramatic.

The actual shift time change between gears is probably very close between the two gearboxes if you just measure the time at 0 torque but the entire shift process the ZF executes (where it ramps down torque, shifts, ramps up torque) is longer than DCT.

This is exactly the feeling I got between my M235i ZF8 and DCT M2 but was probably more pronounced because the tuning was not as good as the G80 ZF.
