This will return a GIF if the client believes that GIF is more than
ten times better than PNG, e.g. because it knows it cannot handle
PNG alpha channels and it thinks there is a high risk that one might
be present but coded as a transparent colour index in the GIF.

This will return PNG if the client believes that it can handle PNG 
at all.

They are not the same.
