Mine is obviously Joe Biden, easily.
I'd rank them as follows:
1. Joe Biden
2. Jacinda Ardern
3. Justin Trudeau
4. Scott Morrison
5. Boris Johnson
This but with Bojo slightly edging out Morrison (purely because he's hilarious)
I am interested why you wouldn’t rank Ardern first.
Mostly because I really like Biden. I'm not a fan of Ardern's zero covid policy but I'm also hesitant to judge it since it seems to work fine for NZ, so yeah it's mostly that I like Biden a lot. Ardern is great though, these two are far above the rest.
