50mm 1.4 Canon or Sigma

I have a Sigma 50mm F1.4

and I didn't compare it to the soft and old canon 50mm
I compared it with the Carl Zeiss 50mm F2 planar and Canon 50mm F1.2L
decided to get the Sigma

If you're afraid of the dreaded paint coat peeling of Sigma, it seems the newer EX lenses uses different finishing than the old ones that's prone to peel, It's better quality and feel.
