How good of a military commander was Alexander actually?

In u/PapiriusCursor’s excellent response to the question of Julius Caesar’s ability as a commander, it’s mentioned that Alexander was “fairly lucky, but that’s another story”. Could anyone expound upon this and tell the story?

Also, follow up, what effect did commanders within Alex's army have on his military success? Ptolemy, Parmenion, etc..

To follow up, how did Alexander compare with his father generally speaking? I mean, was he, or his father, a better general?
