IME saddles do become more comfortable over time, but it's not the saddle that's changing. How I'm sitting, where I'm sitting, pedaling mechanics all play a part.

I'm fine on my unpadded carbon fiber saddle (zero discomfort for hours) but only after adjusting the level and getting used to it. I can say the same for a randomly cheap (~$12) saddle I got online, which I was tempted to throw away after the first time I used it.

Also although we're told that the chamois is just for moisture I've found that biking shorts make a saddle more comfortable especially after an hour or two. Get some biking shorts or MTB shorts if you prefer the more casual look and try that before changing saddles.
