The aesthetics of B&W are super complex and very variable, so the idea that there's a "best" option for a format that covers a huge range of possible effects is indeed unhelpful.

But it's still useful to have some of those effects catalogued and easily accessible as presets. Photoshop doesn't quite do that, which on the one hand makes it hard for beginners to get a good look, but also leaves some space for those who want to go deeper to get more creative.
