Saddles are a very pesronal thing. I have a Selle Italia Trans Am on my road bike and also had one on my cross bike. I find those saddles incredibly comfortable... But I recently put a Fi:zik Pave on my 'cross bike [thanks Marty!] and I'm really liking it. It's a bit narrower than the SI and it doesn't have the love channel, but with the right adjustment, it's amazing. It's a little concave in profile, so when your cheeks are supported, there's not a lot of perineal pressure.
It's also about 1.5 cm shorter than the Selle Italia, which makes it much more convenient for running mounts and dismounts.
