Enneagram Type One and Enneagram Type Eight can showcase some similarities, but they are also quite easy to tell apart. Both are Body types, and both are concerned with the issue of autonomy. Eights want to be autonomous in that they dislike having to bow to powers other than their own. This distaste for others’ control is behind the Eight’s attempt to assert themselves and to force others to deal to them upfront. Deep down, Ones would also like to have the drive and magnetism of an Eight, but they feel they need to justify their autonomy, which is why they mediate it by turning into ‘the right kind of autonomy’, i.e., right action.
This is the basis of the distinction between the two types. Both are highly choleric,* but the Eight’s choler flows free and unhindered, in an instinctual and preintellectual way, while that of a One stagnates inside of them, welling up while awaiting release once it is intellectually justified (but often finding expression in passive-aggressive ways).
In Eights, the energy goes outward and others must learn to live with it, whether they like it or not; in Ones, energy is blocked inside of them and they must try to convince others of their reasons. In this sense, while both Ones and Eights can be rigid and controlling, Ones never try to submit others to their personal power, but rather to the ideal that they themselves submit to.

Both Ones and Eights often hold concepts such as truth, justice, fairness, etc. dear to their heart. Eights, though, have an immediate and almost bodily understanding of them, as they react with immediate action as soon as an instance of injustice or untruth appears before them. Ones, once again, have a more intellectual and systematic approach to them.
Therefore, while Eights are certainly more heroic, they may fail to be able to make finer distinctions even when they are important, thus quickly becoming unjust themselves (you stole an apple, so I’m going to cut off your hand.) Ones, of course, may very well believe in dangerous ideas of justice, but they tend to elaborate them in such a systematic way that a whole society would be able to function according to them, and they would be the first to submit to the system.
Furthermore, Ones may very well be heroic themselves. For instance, my father, a One, has ended up on the newspaper a couple of times for tackling thieves on the street. Ones, however, know that a single act of courage is not enough to substitute a general, impersonal system of rules, whereas Eights may have a more maverick idea of justice as administered by courageous superheroes.
A wonderful example of the difference between Ones and Eights in matters of justice is seen in Plato’s dialogues, where Socrates, the mouthpiece of Plato’s one-ish idealism, often goes up against Sophists who are more eight-ish in their beliefs, wanting to assert the reasons of driven, powerful individuals as opposed to more abstract systems of law. Of course, the story is always told from the One’s perspective, but it is instructive nonetheless.

* I use the words ‘choleric’ and ‘choler’ in the old-fashioned way. Choler is just the bodily energy that leads to self-assertion and is behind our ability to tackle obstacles and enemies. Anger is only one of its expressions.
