Couple of variables....how well you treat the device and how much you will care if it were to get scratched...
Even the toughest screens can be scratched. Samsung doesn't use the toughest so its even easier...or at least less hard.
I enjoy the piece of mind of a screen protector. I have an iPhone for work and I was getting home one day, forgot it was my lap and when I got out of my truck it fell, as I turned I kicked it to make matters worse. The otterbox and screen protector were all scruffed up. I have no doubt the phone would have been destroyed without both of them. This was an accident, I try to be gentle with my stuff but I'm glad I had the screen protector and case because accidents happen.
I'm also the type of person that would hate having even the smallest scratch though...
