I’ve sat in both. I was really surprised by how nice the seats were in the Mustang and the doors were big enough that I could get in without bending my legs which is a huge bonus for anyone with arthritic knees.
The Ariya I felt really comfortable in but it felt like I was perched on the seats. You definitely notice the added height in the Nissan as well.
Which of the two you prefer depends greatly upon personal choice. Drive them both, they’re both great cars.

I'll try to give my honest opinion but am always open to learning.
