Why there isn’t a male vocal trinity?

All music Chanels talk about the vocal trinity: MariahCarey , Whitney Houston and Celine Dione.
And that got me thinking
why no one talks about a male trinity?
Are male singers not as popular as ladies or what ?

Probably in pop we don’t have great male voices, but we have them in rock.

And here would be my trinity, breaking the rule of the ladies that three of them are American with similar singing styles.
The male trinity has a different color of voices and all do rock but different kind of rock.

Here my male vocal trinity

Jon Bon Jovi
Steven Tyler
