Bokeh is an attribute of the lens, not sensor. I'm not sure what this " "greater leap in the "look" of full-frame versus APS" is, either. The biggest complaint most have over aps-c is the change in depth of field for the same field of view. I shot 4x5 film, 2-1/4, 35mm, and when the dslr came out, I shot DX. I could care less about depth of field and related f stops. For me, the most concerning factor about aps-c is the DR and high iso performance. This used to be because of how many photosites are crammed into a given area and aps-c was often a terrible performer over 800iso. Not so today with some Sony and Fuji cameras. The latest Adobe ACR version sure has improved with it's treatment of xtrans sensors as well. Yes, some full-frame cameras may beat some aps-c cameras. My D810 walks all over my Sony RX100, for instance. But my D3s sure gets spanked by my Fuji x-t2. Apples and oranges.
