I have ridden centuries on a few different Brooks saddles, and I personally had a lot more numbness problems with them (male genital version), but I have had better luck with Terry saddles (with a central cutout). They were developed for women riders, but also include a few men's models. I would say people will have to experiment, not just with the type of saddle but also positioning on the bike, getting a taller stem could help shift your weight back on the saddle, onto your ischials, for example; or raising or lowering your saddle (knees permitting).
