Completely depends on the individual.
For example, I love Brooks c17 saddles, but those are hated by some while loved by others.
The saddle width is important, the curve is important, and the nose width is important. All those matter for some riders while others couldn't care less.
A c17 is curved while ergon saddles are flat. I have an ergon and it's ok for 20mi...then is awful.
Best to go to a shop and try some out. Some shops have a rental program where you can try out a demo then buy a saddle from them.
