How does the shape of the Liberty differ from the Hybrid?
Which one (if any) has more or less curvature across the lower part of the face?

I always recommend the Hybrid over the Liberty:

Hybrid and Liberty: Three sizes of nasal pillows.

Hybrid: Three sizes of mouth cushions.
Liberty: Pick one size mouth cushion.

Hybrid: Chin flap which can be used or removed.
Liberty: No chin flap.

Check the prices also.

Here are some tips on sizing, adjusting and modifying the Hybrid - wiki/index.php/Hybrid_Mask_Modifications

As far as I know the Hybrid has the smallest footprint of any full face mask; is the easiest to size because all sizes are included in one package; does not touch or irritate the bridge of the nose; is very stable and leakproof on my face; and you can scratch your nose, watch TV and wear reading glasses with the mask in place.

One big key to successful use of the mask is the ladies tights fix. (Thanks again RG.)

Note that I sleep most of the night on my tummy and parts of the night on my side and this mask is still leak free.

The innomed hybrid, out of the box, great in theory, but I just realized that the nose pillows don' have that signature resmed dual wall layer for better seal. Big problem. Too much of an uphill battle after trying to get a "mask fit." Give me Liberty or give me -----scratch that.

Hybrid just fits me better. I need that chinflap.
