I think there’s 2 basic types of saddle shape, the flatter side-view, convex type (rolls, regal, gobi; arione-sort of) or the scooped side profile, twin-tail grooved WTB / SDG type (also aliante, spoon, aspide, speshs).
Find your arse-match and go from there based on sit bone width and softness.
I liked the 1205 / spoon-flux Aliante copy, ok for a few hours but not all day, but WTB (Volt, Rocket, Laser) are the only saddles I can ride for really long days or more. I’ve fitted 2 of their saddles to my road bike at different times and ridden >100 miles without any trial runs, no discomfort at all. Conversely, I can’t sit on a Regal or Gobi for more than a few minutes.
