How much better image quality do you get with 4x5?

Quick post this time. Before I got my large format camera, I knew that the image quality is much better, that there is much less grain, etc. But I did not know how big the difference would be. I am just blown away each time I scan my large format negs.

By coincidence I shot the same scene with 35mm, 120 and 4x5 film. Here is the same crop, blown up to 1500x1500px. White and black points set, but no other editing. The films are all really different so ignore the difference in grey tones.
