Graphics - You're putting a PS4 game up against an initially Wii U exclusive game? How is that a fair contest?
Sales - Not really. Horizon was at 3.4 million by the beginning of June.

Whereas the Switch version of Breath of the Wild was at 3.92 by the end of June.

Including the Wii U version, it was already over 5 million at that point.
And right now, based off Amazon's Best Seller's List

Zelda is just outside the top 20, Horizon isn't even on the list.
It's really no contest in the sales department.
