TAMRON 35mm vs CANON EF 35mm

Hi everyone, i wanna ask and compare the Tamron 35mm F1.4 EF vs Canon 35mm F1.4 II EF

Im interested most about the image quality/sharpness and quick focusing and reliability between these two lenses, and of course anything else if you know specific about them.

Im going to use one of them when I will decide which one is better on the CANON 5D MK IV
