Neither.
Zelda is better with Takashi Tezuka who directed The Legend of Zelda: Link's Awakening and The Legend of Zelda: A Link to the past.
Miyamoto and Aonuma exceptionally barely contributed on the Gameboy iteration of the Zelda franchise. And the game was a masterpiece. With its compelling and original story (contrary to most Miyamoto's games) It was the TLOU of Zelda on the gameboy IMO.
Too bad Miyamoto and Anonuma probably were so jealous that it was the last Zelda games really directed by Tezuka.
Remember that on top of those 2 Zeldas Tezuka also directed Super Mario World and Super Mario world 2, Miyamoto was just producer on those games. Tezuka also co-directed Super Mario Bros 3 and The Legend of Zelda with Miyamoto; too many people tend to forget those anecdotes and the real contribution of Tezuka on those seminal great Nintendo games.
