I disagree. Perlite retains less water and is better for drainage. But even better than perlite, is pumice or lava rock since it won't break down. Lava rock is heavier, but I use both.
Vermiculite won't break down either. I cant find pumice, lava is pricey, and hydro corn is hard to come by out east.

I know the stuff isn't super cheap, but it's good shit, and I reuse my soil. I got most of my stuff from Build A Soil.
