Easier to clean, I swear they make the cages nearly-impossible to clean. Also a different metal so they don't rust or corrode, I've seen so many gunked up ones. My friend made ones that essentially unclip to flatten out so she can power wash them, flip them over and power was the other side. They work great.
I'd also like to see wire floors be outlawed.
