Family w 3 kids - Choose X or wait for Y?

[Zaxxon]

This is the thing that turns us finally to the X. My family and I are very sensitive to road bumps and really admire well damped cars so the air suspension will definitely be the item that separates us from the Y.
What is the difference between auto and comfort settings?

My understanding is that auto adjusts to be firmer when driving in a spirited manner. Comfort is to be smooth all the time. The manual isn't yet updated to explain these settings further than the release notes.
