That was slightly an oversimplification. I ran out of time to type and couldn't explain myself better.
I've had more trees girded inside tubes than in cages. I've lost a lot of basswood that were in tubes and lost zero of them in cages.
I've used 2 different style tubes. "High Quality" Plantra tubes, and also a bunch of meth tubes that were given to me. I lost no trees in the mesh tubes from girding and mice nests, but, pretty much every single mesh tube was destroyed by deer. I've watched deer "vandalize" them on several occasions. My property is littered with smashed mesh tubes.
The Plantra tubes get mice in them and I also have weeds and vines grow right up the inside of the tube
.
I eventually cage the trees that were started in tubes anyway. I've just come to accept that if I'm gonna cage them someday, I may as well start out with a cage.
But that being said, as usual, growing zone and tree specie has a lot to do with what works for one guy and doesn't work for another.
And I've offered this on that "old forum"... anyone that wants to pay the shipping, can have all of my unused tubes for free. (mostly mesh, and maybe a few Plantra tubes).
