I use more and more fleece each year - i know it doesn't look nice but I have saved carrots, peas, soft fruits and brassicas using fleece as opposed to nets which get tangled up with leaves and unless they are held above the fruit or veg, don't really do the job. Decent fleece can be used from one year to the next - I have even washed mine. So, for me, it's fleece, all the way.
