Object, Property and Region Checkpoints - best one performance wise?

Hi,



I have to write script to test positioning of an image in WPF application.

I found we can use Object, Property and Region Checkpoints are comfortable to compare position. 

• 
  In Property Checkpoint, Left, Right, Width, Height each property has to select separately.


• 
  In Object Checkpoint, Left, Right, Width, Height all properties can select as in single object.


• 
  In Region Checkpoint, we can make mask and mask will compare the result.

Doubt :

     Which is best way to check following position of image/control in UI? Reason?





Thanks in advance.
