I have moved into a new rented appartment and I need to replace the cylinder. The lock is a multilock with a metal cylinder protection cap.

I have a low end cylinder which would fit this lock, I was wondering if I should use the low end cylinder or spend about 40$ for a cylinder simular to the one present now in the lock.
This the low end cylinder:

What is the difference interms of difficulty for a burgular? Is the extra 40$ really help slow the breakin attempt or not? Do burgulars realy pick multilock locks? Is there any difference in time when brute force is used ( drilling the cylinder)?
This question is a matter of principal.
I am not really so sheap or broke that I can't spend extra 40$
