No numbers for the TBM, but here are the basics for the PC-12:
Flight plan for 255 KTAS, 500 lbs for the first hour, 400 lbs for every hour after that.
It will do 250-260 every day of the week- the propoganda from Pilatus says 270 KTAS and it will do it if you run 760 ITT. I like720 ITT better.
I ALWAYS tried to run at Max cruise numbers- I don't have the need to sit in an airplane for more than 6+ hours to see what the range for best economy is....it is quicker to stop for fuel if needed on a really long trip.
We looked at both airplanes and the TBM was nice if we were moving one or two people with no bags; any more than two and the cabin started to get tight. The aft cargo door and tha lav on the PC-12 were GREAT features and selling points.
Support from Socata has been reported as poor at best, Pilatus and the service centers that I've dealt with were fantastic.
TBM will tell you that the 700 is a 300 KTAS airplane. We flew the airplane on two separate demo flights (both 300+ nm) and never saw better than 275.
Clearly, I am very happy with the PC-12 and am biased in my response.
Feel free to PM if you have any other questions.
Good luck
