Saddle choice is very personal. Everybody likes something different. The position on the bike makes a difference too.

I have a B17 that used to sit on my hybrid. It was super-comfortable. When the hybrid was parted out, the B17 made it onto my LHT. I never managed to make it comfortable there. It was sagging by then. I have since moved the B17 to my single speed, and laced it to prevent sagging. It's comfortable, but I don't take that bike on long rides.

I put a Brooks Professional on my LHT now, and although it's better, I'm still not terribly comfortable. It might just be a matter of getting tilt and/or fore-aft position right, or I may have to switch to another saddle.

... or I can hop on my recumbent and not worry about saddles.
