The paddles shifters on the auto are pretty useless to be honest. It's a slow and unsatisfying change, and anyway, you can still use the gear stick to flick up and down if you must. But in my experience, buy the auto version if you want to drive in auto, or buy the DS version if you want a manual and like flicking up and down with paddles.
Having just sold my QP GTS (which are all auto), I'm now left with the MC-Shift GT-S and MC-V GS (which are all paddle-shift), so you can see which gearbox I prefer.
For clarity, I'm not actually against the auto box in the QP, and it definitely suits many people and many driving situations. It's just I don't see the point in having the steering wheel paddles with it.
