No , faster lens is faster but quality is lower , MTF Graph , Color MTF Graph is like crazy. American media publishes weak reports but German magazines are amazing. I was followed them for years at Goethe Institute and faster is worser , impossible to reach some quality point , impossible to control the aberrations.
Buy a 75 year old Elmar and buy a new Nikon f:1.4 and compare if you are knowing what to look for.
Fast lenses are similar to ultrawide angle lenses and they bump somewhere on the road.
Even for Noctilux.
