once again, rent the lenses and see which one you like the best. everyone has their own style and technique which will make one lens appear better than another. the only way to be sure which one will work for you is to try the lenses in your real life style.
This is good advice (style ) can dictate a lot. Like I said earlier with my style I really like primes. Long lenses can be hard to deal with and the more on them can make thing confusing when the action comes in. I really did like the Sigma and towards the end of my rental I was getting used to it. And it has the USB dock these are great but for me time consuming. I shoot thousands of test picks when setting.g the focus points on the Sigmas. I always allow for hits and misses. Then 're test and retest. And when it hits over and over in real world use I call it done. I've very picky when it comes the the sharpness . I view composition over sharpness but why not have both if it's available.
