What is the best Ford S-Max model for off-roading?

I'm looking to take my Ford S-Max on some rough terrain, which model would be the most suitable for off-roading?

I would recommend the Ford S-Max ST-Line X as it has a tougher suspension and improved traction control for off-roading.

I suggest the Ford S-Max Titanium for a balance between on-road performance and off-road capabilities.

I've had success with the Ford S-Max Vignale on rocky terrain thanks to its enhanced ground clearance and hill descent control.
