Also wasn’t Tulkas the greatest warrior? Or maybe he was just described as the strongest. I don’t remember what the books says exactly. However, power and strength/ability as a warrior are very different things in Tolkein’s books. Which is why Tulkas was able to defeat Morgoth, a far more powerful Valar.
Tulkas was the greatest fist-fighter, he beat the shit out of Morgoth with his bare hands.
Eonwe was stated to be the best with weapons, so already that puts him wayyy up there above people like Feanor solely because of that statement alone, Feanor has way more feats and SHOULD theoretically win, but because of that statement alone in a fair fight you literally cannot bet on him to win since Eonwe was already outright stated to be "better" then him and also "better" then literally anyone in the Tolkien-verse that only uses weapons to fight.
Eönwë would have been most likely primarily a warrior and interacted very little with the common folk of Middle-Earth, I think he might overall not have been a good choice since Gandalf was the reason why Frodo went to destroy the Ring and everything, assuming Eönwë had the same restrictions on his power like the Istari did he probably would never have thought about the Hobbits and just tried to take on Sauron with his forces and most likely would have failed.
