There is no correct address to open first

Why the question feels answerable

Almost every set a person meets is ordered. Search results are ranked. Menus put the popular thing first. Lists of options usually carry a recommendation, even an implicit one. A reader arriving at three strings brings that expectation with them and assumes the ordering is there and merely unstated.

So the question forms automatically: which one is the good one. It is a reasonable reflex applied to a set that was not built that way.

What would have to be true for one to be correct

• One would have to reach a different or better version of the market. It does not. All three are routes to one place, which is the subject of the whole equivalence section.
• One would have to be reliably quicker. Speed is a property of the path your traffic takes on a given attempt, not a property of the string, and the path changes.
• One would have to be more genuine than the others. Genuineness is not a matter of degree. Either a string is in the published set or it is not.
• Somebody would have to have measured them all, recently, from where you are. Nobody has, and this site certainly has not, because it never opens them.

The honest answer

There is no correct choice, and the absence of one is not a gap in this site's knowledge. It is a fact about the arrangement. Three routes to one service, published without ranking, present a reader with a genuinely arbitrary decision.

Arbitrary decisions are cheap. They only become expensive when somebody insists on making them well.

What to do with an arbitrary decision

Make it quickly and without thought, and put the attention you saved into the two things that actually repay attention: whether the string you pasted is the string you hold, and what you do when nothing comes back.

A reader who spends twenty seconds deciding which of three to try has spent twenty seconds on the only part of the process where the outcome does not depend on the decision.

Why this is not a dodge

Saying there is no answer would be a dodge if there were an answer available and the site was declining to find it. There is not. The information that would settle it does not exist anywhere a reader could get at it, and any page that offers a ranking is either measuring something that does not generalise or making it up.

A page saying it does not know, when nobody could know, is a better page than one that guesses convincingly. That is also the reasoning behind there being no uptime number here.

The exception that is not an exception

There is one circumstance where a choice is not arbitrary: when you have just tried one and got nothing. Then the correct choice is any of the others, for the obvious reason. That is not a ranking, it is a process of elimination, and it resets the moment you close the browser.

Some readers develop a preference from experience, and there is no harm in it as long as the preference does not become the belief that the other two are worse. The study on habit picking for you is about what happens when it does.

What the absence of a ranking is doing on this site

The three strings at the top of every page here carry no labels, no numbers and no marks of any kind. That is not a design shortcut. Labelling one would be the single claim that contradicts the argument of every study, and once one is labelled the reader stops treating the set as a set.

Why an unanswerable question is worth answering anyway

It would be quicker to say it does not matter and move on. It does not work, because a reader who is told a question does not matter will keep asking it quietly, and will accept the first confident answer they meet elsewhere.

Working through why the question has no answer is what makes the reader immune to the answers other pages supply. That is the actual purpose of this study, and it is why it spends time on what would have to be true rather than simply asserting a conclusion.

What this study is not. It is not a claim that the three behave identically for you, only that no difference you can observe makes one of them the right one to reach for.
