I usually end up using a combination. I like the Summit stick ladder because it has a sort of "srirrup" designed step that captures you foot and helps prevent slipping off side ways say in wet or icey conditions. Usually I'll place 1 to 3 screw in steps to help be exit the ladder onto the platform or hang a pack if I take one up with me. I never leave them in after the season.
As far as banging on a protruding step should I fall from 20-25 feet .... that'd be the least of my injuries I suspect !
