None of them really. Nintendo has never much cared about the continuity, considering they've ignored it, avoided it entirely, or overridden it constantly ever since A Link to the Past.
And yet, the back of the box for ALttP places it before the original two games. The manual even goes into the origins of Ganon and the Triforce, which are expanded upon even further in OoT, which was confirmed to be a prequel to ALttP in interviews. Also, TWW was confirmed to be a sequel to OoT, with the game itself even referencing characters and events from OoT, TP being another sequel to OoT as mentioned in interviews, ST being an obvious sequel to TWW/PH, FS being confirmed to be the first tale at its release, TMC being a prequel to FS, SS being a prequel to everything(made clear ingame as well), etc.
Most games made have explicit connections, either through official sources such as interviews/manuals/boxes, ingame references, or both. This has been true ever since AoL.
There is no timeline that's especially important, valid, or anything like that; none of them matter. Even now with Hyrule Encyclopedia they've essentially just retconned a ton of details from WITHIN actual games, so if the contents of the games themselves aren't even sacred in their mind there's no way between-game connections are.
Aonuma has mentioned in MW that the HE timeline is canon, but the writers of the book said that they took liberties. While the former statement makes it clear that the new timeline(which retcons OoX) is canon, the latter statement means that its possible that some of the details from other parts of the book may not be 100% fact, like the Termina thing that people keep harping on about.
