Oaka's

[Tavrobel]

If I am not mistaken, you do not have to lend him any money for Wantz (not O'aka) to sell the Tetra equipment. He is gonna show up regardless.

Unfortunately, you are, since it is his brother Wantz that sells the Tetra equipment. Wantz can be seen lurking around the party in certain occasions, only if you gave money to O'aka. And Wantz does not sell equipment to the party on Mt. Gagazet, and he does not mention that O'aka was arrested by Yevon (which triggers the sell of Tetra equipment), which triggers his reconciliation with O'aka in FFX, and he heads to Macalania. O'aka will show up at every event plot that he is present in with both outcomes, but he won't sell anything. Tetra equipment is also dropped by 4 of the Original Creations anyway. No offense intended.

Beating Chocobo Eater is easy enough. Beating Chocobo Eater via knocking it off the cliff is a whole different story, which is what I was referring to. The closer it gets to it's side of the cliff, the faster its turn comes. And if you knock it right to the edge, it's turn just magically happens, making it almost impossible to get the final push in unless you have the Haste/Slow combo. Even with this I end up having to heal it so that I don't kill it before knocking it off, but at least it becomes doable. And unless you semi-insanely level up at that point, the only way to have Slow is through the Stunning Steel that O'aka sells.

I WAS referring to beating him by knocking him off the cliff. Overdrive knocks him over, and Lulu/Auron do enough damage to knock him back. Repeat and continue for knockoff. Slow does help, however, but it can be done otherwiswe, with a bit of luck.

Im wondering, whats the difference between knocking the chocobo eater off and killing him?

If you knock him off the cliff, Rin gives you two lv.1 Key Spheres, and the Eater drops a Mega-Potion after the battle, and when he is knocked off, a very funny anime-esque exclamation point pops out of a speech bubble from his head as he falls, and a Chocobo ride is free (the first), and you receive a discount from that point on. If he dies without cliff, then Rin only gives you a Mega-Potion, and the first ride is free, but no discount. If you die normally, Game Over, and if YOU get knocked off the cliff, then you start at the Old Road, with no rewards, no AP, and far from a save point.
