Best lefty off all time? My vote is Koufax!

You're attempting to contextualize and consider all of baseball history with a relatively equal slant. You would expect that to be seen as a good thing on a pre-war baseball board rather than someone trying to play the "real stats" card that went out with Duran Duran.

When you ask a player the same question, you're overwhelmingly likely to get either someone they played against or idolized as a kid. More often than not, they're also basing this on what they personally experienced rather than the total package. In the days before video rooms, what percentage of Koufax's pitches do you think Player X saw?

To be clear, I'm not blaming players for any of this. That's human nature. But to be blunt, player evaluation skills don't necessarily overlap with playing skills. There's a reason baseball front offices hiring pools have undergone a seismic shift.

There is no difference. It is still opinion. fWAR doesn't agree with bWAR. Bill James has Win Shares. Others have their own metrics. It is all personal opinions. Trying to claim that someone else can't use their or other's opinions doesn't work when you are doing the same. Especially when there is no transparency in those opinions.
