In terms of over-the-top reactions to social concerns that they largely made up (ie the meaning of "SJW" before it was ruined and now you have to be nice to SJWs or you'll look like the only kind of person on the internet who's even worse), I'd say it's fedoras.
Fedoras, because they are essentially the foil to the tumblr-style SJW. However, the catch is in the fact that they are more similar to their much-hated Tumblrites than they are different.
For instance, on "This is Thin Privilege", SJWs can be seen complaining about, among other things, that an example of "thin privilege" is the fact that a woman with a body type more closely matching the ideal has better dating prospects. Meanwhile over in the Manosphere, one can see fedoras complaining about men who are "naturals" or "alphas" having privilege (though they don't use that exact word) that allows them a better selection of partners.
Economically, Tumblr SJWs may latch on to a sort of watered-down, severely misunderstood Marxism that essentially replaces "capitalist class" with "patriarchy" and "means of production" with "culture" and that the communist revolution will be only one part of the overall social revolution (indicating that they understand neither Marxism nor feminism) because wealth privilege is also a tool of the patriarchy. Fedoras, on the other hand, unthinkingly embrace libertarianism, because it allows them to think that they're important and powerful, and also to conveniently ignore that no matter how you slice it luck does play a role in your success (as does, to a certain extent, privilege). It also allows them to deflect and claim that it is actually women and minorities who are economically privileged because of non-discrimination laws.
They both demonstrate a creepy fetishization of Asia. In the PUA side of the Manosphere, you get the ideas that "Western Women" have been corrupted by feminism (as if that's the reason they can't get laid, rather than the attitude underlying that exact idea) and therefore Asian women are pure, traditional, vulnerable, sexually submissive, and will do anything you want, and therefore are infinitely superior as partners and you must do everything in your power to get to an Asian woman before the feminists do (the most truly bugnuts insane spin on this that I've seen is that "the feminists" are also trying to pursue the genetic purity of Asian women so that they can have genetically superior followers). At its most vile, it even invokes some eugenics arguments about how Asians are genetically superior and therefore white people must clean up the gene pool by pursuing Asian partners at all costs. On the fedora side, it's much of the same, combined with a deep confusion of how closely anime represents Japanese culture and an attending refusal to tolerate criticisms of anime or Japanese video games based on the claim that the object of criticism is "a part of the culture". The SJWs, for their part, have transethnic Japanese women.
My Asian friends have informed me that all of that is some of the most disgustingly racist shit that they have ever seen in the US.
They both selectively worship and despite science based on how it confirms or refutes their arguments. Obesity denialists will worship studies that show situations in which obesity is not harmful while at the same time criticizing the entire medical field when it says that overall it's healthier to be of normal weight than to be obese. Likewise PUAs and fedoras will happily blow the evo psych trumpet when it allows them to say things like "women naturally evolved to be sexually coy, you need certain techniques to break down last minute resistance [https://en.wikipedia.org/wiki/Rape]" or try to justify flagrantly sexist attitudes with claims that what they are doing is just "acknowledging biological differences", and will accuse of being feminist shills/SJW panderers/"Politically Correct" any scientist who calls that out for the bullshit that it is.
SJWs have "victims of cheating" and the attitude that cheating happens because patriarchy rather than just having a shitty boyfriend, fedoras have "cuckolding" and claim that it happens because of "hypergamy" rather than just having a shitty girlfriend. SJWs have "relationship anxiety", fedoras have the friendzone.
SJWs will try to play Oppression Olympics by saying that, even though they may be white and upper-middle class and attending private college on their parents' dime, they are still victims because they might have to, say, "Know that their race and privilege makes them oppressors." Fedoras will, do the same thing, claiming that they are victims of discrimination towards various subsets of nerd culture.
Basically, both fedoras and SJWs are a bunch of complete nerds with literally nothing better to do than piss and moan about made-up social causes, they differ only in the names that they give to their imagined oppressors.
