Who gave Usyk a tougher fight. Joshua or Chisora

Chisora started like a bull and did ok
From the 4th onwards he did absolutely nothing
AJ despite losing clearly at least looked competitive in the majority of rounds

 

There seems to be a narrative that Chisora barrelling forward, landing nothing of note, and completely gassing out in the second half of the fight means that he gave Usyk a tough fight. In truth, Joshua or Chisora give Usyk zero real problems, but I would lean towards Joshua in the second fight. That round 9 he had was one of the toughest Usyk has faced at HW, but Usyk's round 10 was arguably his best. When he had to shift from second gear to third gear, Joshua posed no issue, nor did Chisora.
