I really prefer datalogging with hptuners over sct. Seems light-years ahead. Maybe dealer SCT is different. To me sct datalogging could be done on a Texas instruments calculator, while hptuners really feels at home on a modern laptop. Much more detail and configuration choices. Unfortunately I haven't found much information when it comes to Ford tuning, so I've been using GM forums and figuring out the similarities that way.
In the end it's up the user to decide what to use and which tuner supports their device. I have a livewire and also a mpvi2, as well as torque pro via obdlink.
I primarily use livewire for daily driving, mpvi2 for testing and learning, and torque pro for entertainment.
