I have a new B17 on my bike and even un-broken in, it is comfortable to me. My first seat was rock hard and uncomfortable. I put a gel padded saddle I had in the garage on after that, and it was comfy to sit on, but I would get chafed because it would "grab" as I pedaled. The new Brooks saddle is firm but doesn't feel like sitting on a rock. It's pretty slippery so there's zero chafing.
I have an Brooks Cambium C17 on backorder which should arrive in the next couple of weeks that I'm excited about trying.
