50mp GFX-50R or S doesn't have much IQ advantage over A7r IV. Only GFX-100 has clear advantage but only if you print in very large size. But guess Sony has next 80~100mp FF sensor in developing that likely better in other areas so will narrow the gap.

I could afford GFX-100 and lenses but I have no interest to build a MF system. FF IQ is good enough, much much more versatile and has much better lens choice. Instead I own three Sony FF cameras (A7r IV, A7r III and A9) and many lenses. I rather spend extra money into trips.

Nobody can answer for you but yourself on your priority.

Check this video, 24mp A9 vs mighty GFX-50s

Despite having got rid of the GFX system, I don't agree with this - it might seem that way from youtubers, but having had both systems there is absolutely an identifiable IQ jump on the medium format.

The caveat is that it is dependent what you are shooting and the environment. Shooting in the street and handheld at distance, you likely won't notice huge differences. Shooting on a tripod, or at higher ISO, or in a studio, or where a narrow DoF is key to the shot, the MF is markedly better - the pixel level noise on the A7Riv against the GFX is hugely different. The GFX50S I had took the cleanest images I have ever taken when it was at it's best, and there is no doubt that the tonality for want of a better word is superior - you will notice clear gradation of tonal change in the MF where there will be only shadow on the FF.

I don't see much difference but actually A7r IV resolves a bit more details than GFX-50s/r in DPR test studio

For DR (shadow lifting), the difference is not that huge especially if compared to 42mp A7r III and 24mp A7 III

For narrow DOF, thought you have more FF option than MF such as 50mm f0.95, 35mm f1.2, 50mm f1.4 (Canon has 50mm f1.2), 85mm f1.4 (Canon has 85mm f1.2), 105mm f1.4, 135mm f1.8.

Per per-pixel high ISO cleanness, then A7s-series is the best

I don’t mean this to be flippant, but have you ever spent any time shooting with medium format? You are supporting my point in a way - if you make this judgement based on the dpr test scene, you’d be forgiven for thinking there’s nothing in it - and sometimes that’s right, there isn’t. But if you shoot with one in a range of situations you will see that there is a clear IQ advantage with MF, when used in the right setting. I have thousands of images shot with both systems that clearly demonstrate it! However, FF carries lots of use and speed advantages that mean it is still the best choice for many people...me included.

Matt Granger found it can rival 50mp MF cameras. I said GFX-100 that has newer BSI-sensor does have clear advantage but not GFX-50 or other 50mp MF cameras.

In terms of image quality—noise, dynamic range, colors—Granger’s first impressions are that Sony’s newer backside-illuminated sensor does a great job keeping up with the larger, lower-resolution 50MP sensors inside its medium format competition.

But then GFX-100 is not that versatile as A7r IV and GFX lens choice although not that bad but nothing close to FF line-up. Still the difference only becomes obvious when you print very big.

I can only stress again that you are basing your view on a youtuber- it may make a decent fist of keeping up with medium format, and it offers many versatility advantages but the image quality is not as good.

True. I am always fascinated by the fact that the most vocal seem to always be the ones who have never owned or used the gear in question....have never extensively worked with files...but instead rely on others, who are often in the same position. Truly bizarre.

Couldn't agree more...
