What is the superior adventure series: The Elder Scrolls or The Legend of Zelda?

The Legend of Zelda, due to it's fun gameplay and historical significance

The Elder Scrolls, because of the open-world sandbox aspects and colossal overworld

The Legend of Zelda, because of the excellent execution of colorful visuals and gameplay that's friendly to all

The Elder Scrolls, because of the sophisticated and realistic visuals and darker story/gameplay

I enjoy both series' equally for their respective qualities, and fighting over the superiority is unnecessary.
