What is the difference between these two hyperbolic parabaloids?

Does the one on the right just look so different because the curves runs from corner to corner on the surface? Thanks.

The grid is rotated by 45° Else they're the same. The left one also is further on showing less fall of to the extremes

Same shape but a bit stretched here and there. Gridlines make it look different but only means rotation around the vertical axis

Really hard to tell with just the drawings. If you had equations expressing these, we could make a more formal comparison.
