In my opinion Foam block do more of blocking wast then filter so they clog the filter and slow down the pump discharge and the water looks for a way around, Whereas polyester traps all size particles (depending on grades and manufactures) and the water flows faster to the pump? Just a thought

I like foam blocks easy to clean.
Of course application plays a big role. But I like polyester fill. It’s super cheap. And real easy to adjust how much you use to change the density of what you are filtering. Sometimes I only have to remove the top layer because of something like,... I just stirred up the tank and lots of crap has collected on the surface of the filter media. With the polyester fill I just peel off the top layer and replace that small amount. Perhaps silly but I feel I get more use out of it Also. In some applications. I need to carefully cut and fit pressed foam pad. But poly fill takes any shape at all.
I can't say I don't agree with Sponge, Poly is a lot cheaper and comes in different densities and a lot easier to change, filter sock getting to be too much work The foam you really cant clean 100%, Poly through away and replace 5minute. done
