Blower type are possibly cheaper to run and slightly cleaner water but need more servicing.
Tbf that motor lasted about 10 years so pretty good as on 24hrs a day
Yes I've always been told the blowers are less reliable, especially if the blower unit is in the tank and not remote. I've never fitted a bio disc. Always different versions of bubblers. With different chamber setups. For the effort of changing a bubbler pump every few years they are so light to install I can't see the merit as an installer of putting in a bio disc
