Ride quality, Air Suspension vs Spring Suspension

[D-n-Tyke]

I apologize, I have searched and didn't really find an answer to this question.

Toying with the idea of adding air suspension to the list of future upgrades. But I realized I have never really understood how air suspension impacts ride quality. What has your guys experience been when switching from springed suspension to air suspension. Did it stay the same? Get better? Get worse? Feel different? Love to hear your guys'z experiences.
