First off, Wojacks ⊂ Rage faces. Rage faces are a wider and more diverse set, that includes the original wojack (and all the wojacks by extension) so they offer more possibilities; both cringe and non-cringe. Beside, they were more often than wojacks used in comics with several pannels and characters. More wojacks are used in single pannels constituting reaction pics or criticisms of a type of people.

In a way, wojacks are the heirs to Rage Comics, but they’ve adapted to a web in which we consume memes more quickly and in greater amounts, hence why they’re suited to smaller templates.
