I sold my Sigma 85mm to get the Canon, and honestly, I'd like to have both of them if possible.
The Sigma is still a kick-ass great lens.
Yeah I know the sigma is a beast of a lens regardless.. Gosh, the decision is so tough. If I do go the sigma route I'll at least have enough money to buy another speedlight and PW set to do some cool OCF work.
I'd sooner flip burgers at McD's before I let the 1.2 go. But that's just me.
I guess I should start flipping burgers
