Okay! Let's take a bet to see which disc falls out and hits the floor first, after some time. I'll bet it's the flimsy cheap disc holding jewel case.
Ok, fine, but while we're at it, let's take a bet to see which disc gets more scratched up after some time too. Those cardboard slits are the perfect way to get a disc all scratched up, while I almost never have that issue with plastic disc holders, not to mention that I take very good care of my discs so I usually never have much of an issue with cases or plastic holders breaking.
