When I got my 997 PDK I really wanted, and searched for, paddle shifters. The first PDK I drove with the standard buttons amazed me. They were really easy to use. I actually preferred them in the end to the paddle shifters which have quite a long throw compared to those fitted in other makes of car I've driven e.g. Jaguar and BMW. I guess its horses for courses but I wouldn't give up on keeping what you've got for a while and see if you can grow to love them.
I ended up buying a car with the paddle shifters as the rest of the spec was what I was after! I'll be having the standard buttons with the multifunction wheel in my 991 when I've saved up the pennies!
