Gravity fed versus pump fed filters

Can't speak to comparison.

We have pump fed.
Pump in the bottom of the pond.
Three feeds up to barrels
Which then gravity feed the VF ponds.
Return gravity to pond
Total head about 4'

Works fine.

Anybody have an opinion on which is better & why? Anybody tried both &
found
one to be much better than the other?

I would think the pump fed is easier to set up & is not sensitive to water
levels in the pond but the gravity fed seems to have the advantage of
being
able to catch a lot of the cack in a settlement chamber and less pump
maintenance.

I'm trying to decide on which way to go - what's the preference of the
assembled company? All thoughts gratefully recieved.
