On Differences Between Max Stirner and Ayn Rand

It's more of a difference in perspective, however there are some substantial differences as well.

I did not read enough of Ayn Rand, but from what I can gather objectivism is just a narrow-minded perspective on work and business. Just a world view from a perspective of a business owner who thinks all he has is solely due to his own effort and overlooks other factors that contributed to that. In the end objectivism just underpins interests of business owners by wrapping them into a somewhat palatable ideology that would justify these interests as something good and benevolent and nothing else.

Any Rand saw Russian Revolution and grew to reject everything it was, the main beef was with Leninist. Thus, Ayn Rand created her philosophy out of rejection of everything USSR and Bolsheviks are. Its die-hard anti-Leninism to to be more preside a reversed Leninism: it's bad because Lenin said its good, its good because Lenin said its bad. Lenin's ideology boils down to benefit for the majority taken to the extreme end often absurd end. Rand replaces it with certain individuals are better than others and the rest should just exist to pave way for such individuals. She also takes this principle to the extreme even absurd end.

On one hand you can sympathize with Rand's opposition to abuses of Soviet approach but at the same time she justifies the abuses coming from the other end that led to October revolution in the first place.

In contrast Stirner's main issue was not with collectivism but with moral that dictates what one can or cannot do. Striner rejects moral and asserts completely unrestrained right to do whatever one wants. Unlike objectivism is not just about business owners and their needs but about everyone.

Stirner opposed to both, people Ayn Rand opposes, but also to people she hails as heroes. According to Stirner there is no need to listen to the likes of Ellsworth Toohey and do good for everyone. On the other hand, there is also no reason to not leech off Dagny Taggard and Hank Rearden if that is in your self-interest.
