Which circle is best?

In order to deem one better than the two others, they all must somehow be differentiated. All three are clearly the same in terms of appearance, so the only way I know to differentiate them is by assigning meaning. Any of the three could probably be considered the best depending on the type of meaning you’re looking for. What’s important is that all three pass through the same meaning filter, each evaluated on the same terms, in other words.

As I tried to fall asleep, I found the right-most circle to be better than the other two. This result is meaningless without including my reason, so: I read the circles from left to right, so that the right-most circle was the last that I saw. Only after having seen this last circle was I able to conclude that all the circles were the same in appearance. This is what differentiates the right-most circle from the others and what makes it best. The first two circles lead me to no conclusions about the set of three because there is one more circle left to see. Likewise, if I read the circles from right to left, the left-most circle would be better than the others.
