I am going to pass some personal opinions on this post which may or may not be agreed by others.

1. There is a lot more to saddle comfort than the saddle itself. You must be measured for the width of your sit bones. A saddle that is too narrow will not be comfortable, no matter what. A saddle too wide can lead to other problems.
2. Adjustments are critical. Saddle height, and fore/aft adjustment are extremely important for a comfortable fit. Just a few mm can make a huge difference.
3. Nose height/tilt is critical. Just a degree or two of or down makes huge differences.
4. Length of ride. I specifically was having trouble when riding more than 60 miles/day. Less than that and I was very comfortable but longer and I was squirming.
5. Riding shorts/bibs etc. Not all padding is created equal. My gel padding was not wicking the moisture on longer rides. I have now switched to Bontrager RXL riding shorts which seem to be much better.
6. Chamois cream etc. This will make a big difference in daily comfort.

I do the majority of my riding on three different bikes with the longer rides being mostly on a roadie and a hard tail. The setup can be very different on bikes with different geometry. Be patient and your rear will thank you.

I have not tried a Brooks and cannot speak on their behalf.
