No doubt, if the 85 prime will be one of your main shooting lenses--the one you will consistent depend on, the 85L is the way to go for build quality, consistency, and service.
I personally use 85 primes only once in a while (preferring the 35L and the 70-200L) and so the Sigma works fine for me when I am looking for that focal length.

Im debating on this right now, sell the 85f1.8 for the Sigma 85f1.4, now I am not so sure after reading this. MIght be better to put upgrade money into the 70-200 II. I have no issues with my Sigma 50f1.4 on either my 7D or 5D3.
The versatility of the 70-200 ll blow the doors off any prime 85.
