Photoshop vs photoshop elements?

[JustJazzie]

I've decided that with the direction I'd like to start taking my work I would really benefit from liquify, so I am looking Into photoshop to sidecar my aperture workflow.

I see that elements has a liquify tool and it can merge photos (right?)

Anyways, can someone explain why I would want photoshop over elements?

Aperture seems to do everything I need it to except liquify and merging photos, but I'm sure there are plenty of features I don't even know I need.

Elements is limited to 8-bit depth editing, while CS/CC can do 16-bit depth edits.

How important is this if I am ONLY using it for the above mentioned uses??
