Is Jungkook's voice the closest we have to mainstream western male pop vocals?

In Kpop.

Any other male idols who have such mainstream pop oriented vocals like him?

yes

he's the best!!

Taeyang from Bigbang has always had a western feel to his vocals, he's heavily influenced by western artists.

Idk. His voice is just boring tbh so if you consider western male artists vocals as "boring" then yes.

yes. anyone who says his voice is boring or subpar has clearly only heard a small fraction of BTS' music.

Is that supposed to be a good thing?

he has a universally appealing voice but idk if he sounds western per say

Yes!

No.

If you mean the perfect pop voice then yes!!

Nobody can touch him in kpop and the koreaness adds to his charm. Nobody like him in pop right now. His solo will blow records.
