Preferred Anglospheric conservatives?

...and why?

I'm not naturally a supporter of conservatives, although I'm also not automatically going to vote against the right wing. For me, the parties of the anglospheric right all seem to be somewhat ideologically united for now, certainly compared to their past. Obviously they are all still big tents, as has always been the case with the anti-Labor movements in the Commonwealth realms and with the Business-religion alliance in the United States.

My personal order of preference:

NZ Nationals
AUS Liberals
UK Conservatives
CAN Conservatives
US Republicans.

Big gap after the Brits, huge gap after the Canucks.

(I should also note that if this were about the party leaders, the Liberals would move to last presuming Boner was Republican leader)
