Sigma 300 versus Canon 300

I posted this in another forum as well but I wanted to get as much feedback as possible given the $3k difference in prices.

i’m in the maket for a 300mm 2.8 lens. I primarily use the lens for football. The Sigma 120-300 2.8 has grood reviews but I rented it on two occasions and both times the images seemed soft and less vibrant than the Canon 300 2.8. In particular facial details under the helmet seemed noticably softer with the Sigma. Could it be user error? Maybe but the same user (me) is taking the pictures so that shouldn’t matter. It was afternoon and I was shooting at perhaps 3.2 or 3.5. Another explanation is that the rental place’s Sigma is a bit off.

So for those who have used either, do you really get sharper pictures if you pay the $3k extra for the Canon? What am I sacrificing if I buy the Sigma? Thanks!
