I also get the argument tho that modern FF digital is "good enough" for mostly everything and close enough to MF film in terms of output - doesn't mean a bigger MF digital wouldn't one-up it, though. The question is just, "how much?"
But otherwise... all else equal, a bigger sensor will have better colors/contrast because for any given equal size magnification it captures more light (photons/"information") than a smaller sized one. Just look at how different the images between 135 and 120 film look, where the "sensor" is identical.
