>>713663753 (OP)I kinda dislike the classic FFIV logo, it's just Kain, he's an important character I guess but he's not even the main one, relevant to the overall plot about Lunarians nor he's the main villian, the DS logo makes much more sense but it sucks it was never used again outside of that particular version (The 3D version).
Also not a fan of the III logo either, it's a vague character as a warrior dual-wielding some swords (Well, he DOES look more like the actual Warrior class sprite than the FFI logo), the Onion Knight is much more iconic but it doesn't represent anything important to the plot, the crystal tower or a floating island would've been a better choice.
Best one is probably either VI, VII and X, classy, represent something about the plot or main character/narrative and look sick as fuck.
