How is anime and manga more popular than comics and western cartoons?

Not against the medium I consume it.

But it occurred to me that there seems to be a lot more exposure to anime and manga largely thanks to services like crunchyroll and manga reader services, this includes physical sales as well.

It's just that you'd think say, Superman would be more stupidly popular since everyone knows who he is than someone such as Lelouch from Code Geass.

Is it because comics just doesn't have the same spark with the younger generation? Or is it because there are a billion different issues of comics so it makes manga more streamlined?

I would like to know your thoughts as I am quite curious about this phenomenon, since even in the early 2000s I was into anime, and you could get your fix from non legit services via the Internet, but I'm sure as shit it didn't hit this mainstream until the mid 2010s and now the roaring 2020s.
