The XT3's mechanical fps is 11 - just like the A6600. The higher 20fps rate is only when using electronic shutter - which for many fast moving tracking subjects cannot be used due to the slower shutter readout causing jello/bending effects. 30fps is strictly when using a sensor crop mode. Whether those 'faster' burst modes are able to be used is where the subjective comes in. If I need mechanical shutter for my subjects, both cameras deliver 11fps, and one has significantly better and more accurate tracking focus resulting in a much higher hit rate on erratic subjects, then that camera is clearly, objectively, going to meet my needs better.Objectively 15, 20, and 30 fps are better.
Not that much, and the A6600 still comes out in a vast majority of reviews as superior in focus tracking compared to the Xt3. And many reviews will point out a significant difference - not a small one - for tracking tenacity, accuracy, stickiness, etc.AF on the A9 and A9ii. Not the A6600 or A6400. There is a big difference.
If your goal is to just find things on spec pages that are 'objectively' better for the A6600 vs the XT3:If you can find things on specs pages where the Sony are better, please show us. It would be helpful.

Now, each person can decide if any of your list of 'objectively better' things, or my list of 'objectively better' things, matters to THEM and their own shooting needs.
