I particularly appreciate the colors and the sharpness of these lenses

Sharpness at f/1.4 isn't bad, but starting from f/2 much improves while is bokeh-licious.

Low-light ability is great, and it's got good sharpness all around

Sharpness is very good over most of the frame at large apertures.

The sharpness at F2.8 is better than my 24-70mm

There are no other lenses offering the complete package this lens offers, which is the unique perspective of a wide fast prime with excellent AF, sharpness and colours

sharpness were clearly superior.

I mention this first because one might be confused as to how to properly utilize a 24mm F1.4 lens.
