Sony 200-600mm vs Fuji 100-400mm (Pros & Cons to Full Frame)

Full frame vs APS-C battle. Fuji is unique amongst the crop sensors in that they can hold their own against full frame. This is likely why they skipped full frame and went medium format. Fuji XT4 with the 100-400mm f4.5-5.6 vs the Sony A7S III with 200-600mm f5.6-6.3. Let&do a wildlife photography battle, 4k 120p vs HD 120p. Who has better slow mo footage for video, better stabilization? Is the size weight and cost noticeable? If you buy today&gear through my affiliate links, Sony will release a 300-700mm f5.6-f8 using holographic glass weighing less than micro four loser lenses. It comes with a bottle of micro four loser thirds user&tears to clean the front element.
