I have no data. BUT, coarser bubbles will keep a bigger area open due to wave action. An air stone will need more maintenance than a rubber membrane disk.
Rubber - shut off air, scrub with mild scotchbrite pad or dish cleaning pad, drop down, turn air back on.
Air stone - I think of bleach or acid to clean the pores.
When I used to work at the aquarium we would soak the air stones in bleach to clean them.
