I have a Danny Gray buttcrack on my 02 SS, full leather and surprisingly comfortable but after 100 miles I'm off it anyways. I had a Badlander and it was like sitting on a flat rock.
If your talking about the 2020/2021 Softail Standard, my wife has a 2020 and says the seat is great. The suspension plays a big part of that I'm sure as the new Softails suspension is night and day better than the older under frame mounted suspension.
