Pumice versus Perlite

They both aerate the soil, both hold nutrients, and both cost about the same retail in small quantities. Any opinions about which is better? One thing I don't like about perlite is its so light it floats on water, and tends to separate from the soil mixture and rise to the top when watered. I believe I read pumice lasts longer.
