COP vs. CPS Which is Better?

The CPS locks the data in copy elements (inputs) form changing while the copy completes.
Are there any other advantages of using CPS over COP? Also, How much time will it take to copy an array sized 320 to another array using CPS?

I have always used COP. and it has worked for matrices of different sizes.
I am going to simulate with the CPS instruction and I will inform you about the results.
