Canon 85\1.8 or 50\1.4, which lens has better background filtering?

Of course, the blur of the 85 is better. First of all, the focal length of the 85 is longer, which can bring a shallower depth of field, making up for the weakness of the slightly smaller aperture than the 50. Secondly, 85 has an 8-blade circular aperture. The blur is much more natural and better-looking than 50, which looks a bit messy. And there is obvious bilinearity. The aperture is not round and looks unnatural. I have both lenses, and when shooting portraits I usually use the 85. 50 is a little used.
