Unless your height is in the top or bottom five percent for adult humans, you don't need an adjustable-height desk.
The Sense desk (with its optional hutch) appears to cost approximately the same amount as the EDU, but the EDU is hugely more attractive. It's like night and day; the Sense looks fine for a commercial office or a utilitarian home office, but the EDU is a design classic that really looks at home in a home.
Although the EDU has only a single shelf and file drawer for storage, that storage is below the desk and easily accessible. The Sense hutch, on the other hand, eats up a third of the desk's depth, and even a small computer monitor on the desk will block your access to much of the hutch.
If I were in your place, I'd buy the EDU without a second thought.
The only disadvantage of the EDU is that its desktop surface is more fragile than the laminate Sense desktop's... So if you do choose the EDU, buy a glass top for it immediately; the dimensions are 28" x 60", with a 3/8" radius on the corners. Don't do what I did:
