I know a pro friend that tried the Sigma and liked it, but chose the Sony and with a Sony 2X teleconverter can have a 200-800mm lens which he loves for Bird and wildlife photography.

FYI, I have owned a few Sigma lenses and they are excellent, and I currently have three, Sigma Art 24-70mm f2.8 DG DN, Sigma Art 70mm f2.8 Macro DG DN, and Sigma Art 85mm f1.4 DG DN lenses, along with Sony and Tamron lenses for my Sony A1, A7RIV and A7SIII.
I did own the Sigma Contemporary 150-600mm lens in EF mount, which I used with the MC-11 adapter on my Sony cameras. It worked pretty well, but I eventually sold it when the Sony 200-600mm came out and the Sony is superior in many ways.
