BobbyTomek,
wrong again...and after having spent more than a quarter century relying on good glass to make a living, I'll state I can critically compare from an unbiased standpoint, too.
I am extremely picky when it comes to optics, too -- moreso than necessary, I might add.
Then you would know empirically, like I do, that a Swarovski z5 can be way better than a Swarovski z3. If the z3 I compared my "good" z5 to was a "bad" z3 then that could be the reason it was infact what happened and you would not have gone into attack mode.
