I tried a couple different nets, they always sagged really bad on mine and collected snow and leaves, and collapsed multiple times. Now I have “snow fencing” and use a blower to remove leaves and snow, but it has definitely worked much better. Small wild birds and squirrels can usually get through without problems, though I have had the squirrels chew a few openings in corners and such. As a plus, it seemed to be much cheaper too. It’s definitely more durable.
This stuff (I got the green, a little more camoflauged and not so obvious from a distance).
