As suggested, try on various saddles at the LBS. Buy one maybe. With a lot of luck, you'll strike pay dirt the first time. More likely you'll be trying on something else after 50-100 miles. Brooks is so popular for a good reason. Might up your odds of getting it right the first time by biting the Brooks bullet. If you do, follow the break in instructions exactly. And persevere.
Every saddle has a sweet spot. Find it by tweaking the rail position and tilt. This won't work if your bike is not a reasonably good fit, saddle to bar.
