Make sure no opinions are present in this conversation! (singles format for convience, post another for doubles specifically if required)

@PX If the answer is completely format-dependent, and the person who asked the question never told us the format, is that a reason to hide this question?
I never deemed it format dependant, the answer goes by competitive viability, i.e which is usually or generally better in its current sense, which while sometimes affected by format in lieu of specific uses and niches, can still be listed and stated as being overall more or less 'viable'. I don't require specifics or in depth reasoning if the question also doesn't ask for it. The question and answer are both fine, and if you think otherwise I'll pass any complaints you have along
First, all of the abilities that only work in doubles are obviously format dependent, right?
Even between different singles formats, the rules are so different that I think it is often impossible to know if something is "generally" more viable than something else. If there was, why do different formats have different viability rankings? Specifically, Snorlaxes in RU usually have thick fat, but thick fat Snorlax is nearly useless in BSS compared to gluttony Snorlax. Same with trace Porygon2 in RU and download Porygon2 in BSS. Moody Glalie is okay in some official formats but completely banned in all Smogon formats. Of course, I didn't look at every Pokemon, so I don't know exactly how often you can say an ability is "generally" more viable than another ability. I just wanted to say it's a lot less than 100%.
Then an answer should distinct between singles and doubles if prompted by the asker, and don't if they don't. It's really not complicated. There's no reason for this to be taken down imo, if another auth disagree they'll do something. Hell, if it makes you feel better ill specify singles in the title to make sure it's allowed, something we're and you're allowed to do yourself you know
The entire second paragraph of that comment was about how there might not be a good answer even if it specified singles...

If Nidoqueen/king's sheer force is better than their regular abilities, why did you mention them?
I think Clefairy is viable in several double battling formats purely because of friend guard. It even says so in your own source. https://www.smogon.com/dex/sm/pokemon/clefairy/vgc18/
How do Vileplume and Bellossom have better hidden abilities?
How is Arcanine's justified better than its intimidate?
How is the Machop family's no guard dynamic punch not good?
How does the Ponyta family's flame body activate more reliably than flash fire does?
Is power of alchemy ever useful in singles?
If Alolan Exeggutor's hidden ability is better, why did you mention it?
Why does the Lickitung family hate weather so much?
How is Chansey's hidden ability useful in singles?
The Goldeen family has lightning rod, not damp.
Are you really expecting Kabutops to survive an attack and activate weak armor?
I metioned Nidoqueen/King and Alolan Exeggutor on accident. :P

Edited. :P

I  didn't say Arcanine's justified is better than its Intimidate, I said the opposite, actually.

I didn't say the Machop family's No Guard wasn't good, I said the opposite, actually.

I don't think either of Ponyta's abilities activate better than the other, and therefore don't think either are "better". :P

Does the Lickitung family ever really need Own Tempo, though? Confusion is way less effective than it was before and a weather canceling switch can help shut down or hinder weather sweepers, at least. :P

I didn't say Chansey's Hidden Ability was useful in singles, I said the opposite, actually.

Goldeen was listed having damp in the bulbapedia article; I see it has Lightning Rod from looking elsewhere. :P
Your answer still doesn't mention Vileplume, Bellossom, Tentacruel, Dodrio, Mr. Mime, or Kabutops.
Flash fire doesn't depend on luck to activate, so it's better than flame body.
Lickitung and Lickilicky don't use own tempo, either. Their best ability is oblivious, which prevents taunting.
@Stakatacool, isn’t flame body pretty good on ponyata’s line?(I was asking about hidden abillities that are worse than regualr abillities)
Flame body isn't a good ability because it has a low chance of activating. Rapidash's defenses are so low that it'll usually faint before it can activate flame body.
Also, Weavile's pickpocket is really bad, and the only reason Reuniclus is ever used is magic guard. Why are you including Buneary if its hidden ability is the good one? Also, this answer appears to ignore the fact that a mega evolving Pokemon still needs to pick either a regular ability or hidden ability before mega evolving. The fact that the pre-mega ability disappears immediately leads to some complications and extremely situational choices.

Both Charizards carry blaze in case there's sunny weather before it mega evolves.
Gyarados prefers intimidate over moxie for what should be obvious reasons.
Mawile prefers intimidate over sheer force for what should be obvious reasons.
Medicham carries telepathy in case a Ditto tries to impostor it before it mega evolves. Regardless of the pre-mega ability, it'll mega evolve and gain pure power before it uses any attacks.
Pinsir carries hyper cutter in case someone tries to intimidate it before it mega evolves.
Scizor prefers light metal because low kick is the most common weight move.
Swampert carries damp to stop the occasional explosion.
Justified is better in doubles, because of beat up you can get ridiculous attack in a turn.
