Sony a7r iv Vs a99ii

[sonikos]

Hello I need the help of the fellow members of the forum. For wildlife photography I'm considering two options:

1) Sony a7r iv + la-ea5 + tamron 150-600mm,

2) Sony a99 ii + Minolta 600mm f4

Which one would give me better results in image and most importantly in cropping.

Thank you very much in advance.
