Ganondorf wins way too easily. He's way too durable/powerful to be beaten by Bowser.

And before anyone yells that Bowser has withstood a black hole/supernova, I'd like to point out that in the end of the Mario Galaxy (I honestly don't remember which one, but whatever), when he was hit by them, the Lumas were actually using their power to protect everyone. Which is why the universe was fine from being inside a black hole. Notice how that wouldn't make sense otherwise. Everything in the Mushroom Kingdom was untouched. And being untouched by a black hole? How about no.

Ganondorf, on the other hand, is completely unkillable by anything but the Master Sword, a weapon that doesn't exist in the Marioverse, and even if it did, Bowser would be incapable of wielding it. Though in the original Zelda, Ganondorf was defeated by the white sword, it was still an extremely powerful light magic weapon. Bowser wields dark magic, which Ganondorf could easily defend against with his Sword of the Sages (Which was also used in his attempted execution, which failed spectacularly when he survived it, broke his restrains, and then killed a god-like being with his bare hands), as it is also a powerful light-based weapon, which couldn't kill him, rendering the original version's weakness pointless to mention. Ganondorf also took a violent attack by Link in Wind Waker with the Master Sword, after which Ganondorf casually slapped him aside and told him that the weakened Master Sword couldn't harm him. Then, to make matters worse, Valoo burnt the Forsaken Forstress down. Guess who still laughed it off? Ganondorf.

So in the end, no matter how powerful/durable Bowser is, Ganondorf would remain unaffected by anything Bowser threw at him, and Bowser is, as everyone said, defeated by lava. Though not always, this renders him to Dry Bowser. A reanimated corpse, meaning he was previously dead. Ganondorf withstood dragonfire, which incinerated almost the entirety of the Forsaken Fortress, untouched, while Bowser has been canonically defeated/killed by being thrown into lava. Plus, Ganondorf is only ever really sealed.

In Ocarina of Time, even after getting decimated by Link with the Master Sword, having his entire castle (Several thousand tons of stone) falling on him, he was fine, then turned Ganon, who was ALSO alive after having the Master Sword driven into his face to the hilt. Only to be sealed and to break free a little while later.

And all of this isn't including Ganon's abilities. Bowser vs Ganondorf, Ganondorf wins. Boswer vs GANON? Ganon rips the Koopa King's spine out of his throat.

And yes, that is a literaly possibilty considering his brutality against the sages, crushing one of the god-like beings in his bare hands (Who shouldn't have been able to be killed in such a casual manner)

So, need I go on? Ganondorf is pretty much invincible to everything Bowser can do while Ganondorf has tons of ways to kill Boswer... like banish him to another dimension. Yeah. He's done that.
