I going to burst that bubble. Every choice you make comes with risks.
If you can't make good images with the 300-600, it may be time to work on technique. I have both the 400 2.8 GM and the Sigma 300-600. Both have pros and cons. Sure, the 400 2.8 works better in low light, has a fast FPS and a slightly faster focus. But if the subject suddenly gets close to you, the 400 may be too tight and you end up chopping body parts that you didn't intend. Sometimes 400 is not long enough and you don't want to crop as much.
Some from the Sony A1 and Sigma 300-600 from the other night.
The 300-600 is more than capable of making images
Capable does not mean it's reliable and fast.
Do you ever zoom in/out while AF-C? I guess not which is an important issue with 3rd party lenses and I assume you are using it like a prime lens. If you are telling me to use it like a prime lens, then it's already pointless.
