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.
Adam Lambert of course. He is technically flawless. But unfortunately he wants to sing uptempo pop music, which his voice is simply not suited for.
Tiziano is the best contemporary example of an incredible voice and music that fits that voice.
Quante ne vorrei fare ma poi rimango fermo
Guardo la vita in foto e già è arrivato un altro inverno
Non cambio mai su questo mai, distruggo tutto sempre
Se vi ho deluso chieder scusa non servirà a niente
