Who had more power : George III or Donald Trump ?

Difficult to compare due to the different eras. George III had huge power but actually he differed to Parliament mostly in the same way that Charles III arguably has now but again he defers to Parliament. Parliament is sovereign in UK as delegated from the monarch. Whereas Trump has executive powers the UaK prime minister would never have. Prime minister is only prime minister at the behest of Parliament. Hence why Boris Johnson and Liz Truss had to go without elections, we dont elect the PM they're invited to form a government by the monarch.

Also Trump has direct (unilateral?) control of the largest nuclear arsenal. So that gives him way more power than George III could ever had thought of.
