Navigation order for cancel and save buttons

I'm currently defining the order of tab navigation for a form. At the bottom of the form there are two buttons, "Cancel" and "Save". Following the tab order from left to right, the first button to gain focus would be "Cancel", But the primary action of the form, and the most used is "Save".

What would be a better experience, finishing the form and going for the cancel button, or go directly for the save button?

Also, if going direct for save button, another tab would go back to cancel or go to the first field of the form?

Here is an example of both paths:

Thanks!
