Are you going to be the pilot. If you are and have a descent amount of single pilot experience in a fast twin in IFR then Commander is OK. If you have limited experience go for the PC12, it will be safer for you and your family and that's the main thing I expect.
Have about 2000hrs in the commander and about 1000 in a caravan (yeah not a PC12 but expect similar) If you are going to fly don't let your ego endanger you family if you are not going to stay current or have limited experience, the PC12 will probably be easier to fly than a 206 or 210, the commander can get you into trouble very fast.
