I would do 6speedonline.

You have to first choose whether or not you want manual or PDK and how much modding you're going to do.

The 997.1 has the Mezger engine that is usually the choice of heavy modding. To get the most out of it, you have to go manual since the PDK has a lower threshold of what HP it can handle.

If you wanted the updated PCM, rear tail lights, minor updates then I would get the 997.2 in PDK. The PDK is supposedly updated in the .2 wit the DFI engine. To me, there is less lag in the .2 stock for stock. The suspension feels updated too but no one can confirm.
