I have the regal. So next line up. The classic has been around for a long time, and not much has changed on that design. So honestly, it must be doing something correct! As for quietness, unless you upgrade that pump it may hum a bit. Lots of people complain about the skimmer hums but it’s the vibration from the pump. My skimmer uses the varios pump and it’s super quiet! Can’t hear it at all like it not even running. So if you can upgrade to the regal, or upgrade the pump you’ll be happy
