I’ve had a limited amount of time with the GFX100S II but have owned the A1 , GFX100S and A1 iI since launch so take this with a grain of salt but there are a couple factors in play that tilt the scales for my use cases towards the Sony. I did find the 100II AF considerably better than the 100S and hand holding the 100SII with the improved ibis better but not night and day better.
1. Faster glass. My fastest GF lens is 1.7. I can get away with either lower ISO or faster shutter speeds with the A1/A1 II shooting faster glass.
2. Useful ES - shutter shock free with the Sonys. Not the case with the GFX.
3. Slop factor. IMO there’s less margin for error with 102mp vs 50mp.
Of all my cameras for ibis the champion is still the little Oly OM-1. Awesome for stabilization.
Just my 0.02
