The hybrid tune is a little easier (from what I've been told, I am not a tuner) to tune for driveability since you don't have to try to figure out parameters for the car to guess how much air it is getting. At low RPM, the ECU uses the MAFs to see exactly (theoretically) how much air the engine is taking in to adjust that way. Full SD is more time consuming due to the "guessing game" for air across the entire RPM range vice a specific one (i.e. high RPM/load of racing).
Driveability is a function of the tuner, in my opinion. A full SD tune can drive like stock with enough patience. A hybrid tune will get you that faster is all. If you look at your logs when you do WOT pulls, there is the Speed Density Digital (on/off) parameter that should switch "ON" at a predetermined threshold and then back "OFF" when you fall back below the trigger point.
