Out of today's male popular musicians, who is the best vocalist? Who has the best vocal technique? Whose vocal skill is the greatest? Who are the male answers to Whitney Houston, Mariah Carey and Beyoncé?
I'd say Adam Lambert is the only male artist that does acrobatics like the females you just described. In modern rock we have Jared Leto and Chester Bennington that are excellent too and kinda do vocal acrobatics too, their range might not be as wide but sometimes they show a lot more control and restraint than Adam.
There are other with beautiful tones though, like Bruno, Bublé, Josh Groban, the list goes on.
