My opinion - both.

The Lithia is squishy and more likely to cause soft tissue chafing and pinching.

When I switched from a Lithia to a Jett, it really changed the way I sit on the bike, and I had to tweak the stem, handlebar tilt, and lever placement, and IIRC the fore/aft placement of the saddle, too. So if you were fit on the Jett, you might have to re-do the fit to be happy with the Lithia.

You wouldn't think it from how similar the saddles look, but that was my experience.
