Shape (curvature back-to-front, side-to-side as well as tear drop vs. T-shaped), padding and shell stiffness are at least as important as the max width of the saddle.

Case in point, the Antares did not work for me because it gets too narrow too quickly in the middle. I rotate my hips forward and rest most of my weight on my pubic rami, and the Antares did not support me properly, even though it is quite wide in the back. I also have an old USPS team replica SSM Aspide which supports my sit bones quite well even though it is around 15mm narrower than the Antares. Then there is a newer Aspide Racing Team saddle I picked up to replace the old worn one and it is around 5mm wider than the old one, but much more flexible in the shell and it doesn't support me as well as the old one - I'm actually thinking of retiring it prematurely and re-covering the old Aspide instead.

As a few posters already mentioned, how one sits makes a lot of difference.
