I think it would be another close to call fight
People see limitations in Joshua, part because they are weakness, and part because he's not been tested by opposition. His head movement at times isn't great. It will be a big big test for Joshua against Fury, same as it was with WK, it's the first time he's facing boxers of quality that are physically similar (or in Fury case taller). Earlier opponents haven't been able to get close enough to do any real damage, or work off a jab properly. WK and Fury both do this, and both will be able to exploit AJ weaknesses
Last night will have been a huge learning curve for Joshua, and would expect him to be better if rematch with WK or a fight against Fury or Wilder, he would be tested as all three are too high a standard not to test him, same way that for them fighting AJ would be a huge test and challenge for them
