Comments sections on wikis there for e.g. FromSoftware games can tend toward rebarbativity, and the ads can be annoying, but in my recent experience the information troves compiled for big games such as Elden Ring are an indispensable resource.
The initial Dark Souls wikidot was excellent. Fextralife bullied and threatened them into closing down. At this point, people don't move on because of habit, but the quality for the Elden Ring wiki is dramatically bad. Information is outdated, poorly maintained, actual fixes are being reverted by their own, paid editors, other wikis are suspiciously often the target of attacks and deleted content.
But I haven't experienced problems with information in the guides. Off the top of my head: for Elden Ring, Bloodborne, Sekiro, and Hollow Knight, I don't recall a single time when the info was flat out wrong. In the case of comments pointing out something incorrect or incomplete, it had already been fixed by the time of my reading.
It also highlights an important difference between why wikis can be useful. If I want information about Elden Ring as a game, Fextralife is pretty good (with some ublock filters to kill the stupid chat), but it does that at the expense of information about Elden Ring as a fictional world. That's not usually why I'm looking up Elden Ring information, but it sometimes is.
Truth be told, it appears that Weird Gloop/mediawiki has a bit of a monopoly on wiki platforms that don't suck.
