Goats is pretty secure. Everyone knows that right? I challenge anyone to disprove this.
Proof for me is in the above dialog. I'm not sure I know of any products out there that use Quality Levels greater than 8, while there are many that use Quality levels 1 to 7. Eight is better by the way, than 1 through 7, though not as good as 9 or above (if they exist at all).
