HDFC Power Biz Vs Regalia Gold vs Bonvoy CC for Domestic Lounge?

[Vickyakhan555]

I am getting offer to upgrade my LTF Business Regalia to paid Power Biz cc?


Is Bonvoy credit card on Diners network good for domestic lounge? Or regalia gold?

As I heard Diners card acceptance in domestic lounge across india is not good. Kindly suggest
