We have an old Laars LX400 that still works but is noisy.
Mostly blower noise and vibration.

Im trying to determine if newer heaters are any Quieter ?
Ive googled and googled

Im guessing some of the vibration comes from the age of the unit and stuff not being tight

My Nieighbors have asked what we have running and my SO says the noise gets in the way of watching TV in the back yard ...

The equipment is all in side yard about 25 feet or less from the pool, there is a small fence that visually blocks the heater and equipment from the pool area

You can try tightening as many connection points as possible. The fan blade may also be dirty making it unbalanced. But that is more work to access it.

Take care.
