Hiding And Disabling A Field With A Condition

All my fields are required, but some should be skipped (and not even shown) based on conditional answers. Is it better to use conditions to show the fields and make them required if XYZ, or to enable them if XYZ? What's the difference between hiding and disabling a field with a condition?

Hiding a fields will make the field disappear from the form. Disabling a field will still show the field, but will make it like read only. So, the user wont be able to input data.
