I agree that it sounds different but I find that it is also better - not surprising. I would generally tune each instance to suit the particular application in FAT mode.
The problem in a host like Cubase SX 3 is that as soon as you switch on an instance - even with the transport stopped - the full CPU load is incurred. The Auto switch gets around this by letting you set up a mix with multiple instances active and then do the offline render.
