****  Not so easily answered that way at all.

It's true that any stereoscopic view incorporates two views because we use
two eyes no matter how many images may exist covering the entire scene.

So is two lenses best?

Consider that a multiple imaged lenticular allows a greater deal of movement
of the head with a greatly reduced sense of spatial distortion. This is
because a multi-imaged lenticular lets you see around objects slightly
before the cycle of images repeats. That provides an edge to the
multi-imaged lenticular over a single stereo pair of the same picture. At
least it does if ortho-ness and a sense of reality is important, and
absolute resolution issues aren't being compared.

Consider the commercials that hold an object like a car with splashes of mud
hanging in the air while the camera appears to take a stroll around the
image... You can only record one pair of images with two lenses. If you want
a greater walk around effect, more lenses is better. 

Maybe lenticulars is not the best presentation method for every purpose, but
a wider range of recorded images affords choices a single pair just doesn't
have. I'll take as many lenses as possible as the *better* option, taken on
a theoretical basis.
