MojoHand,
Those are simplistic statements not meant for the real world of optics consumption. Otherwise we wouldn't have the variety of very good scopes of myriad descriptions available.
Some people install expensive glass just so they can brag about them. Some want great glass and great low light performance and reliability and high magnification and consistent tracking for playing with their turrets and toughness in case of falls. Some take the package optics and are good to go for the rest of their life.
Some don't realize the scope they have is not as good as when it was first installed. I know because I thought my barrel was wore out when the groups opened up while using a Burris Signature 8-32X on my .223. Fortunately a friend suggest I try another scope. The groups went back to normal.
