Let's add another for er32 , you don't have to reach up top to change the collets or tooling . I say that because from a wheelchair ITS easier.
Experiences vary and anything that can happen, probably will happen. I've had end mill holders slip enough that I avoid them in preference to an ER chuck that has never slipped. A collet will also grab concentrically, while an end mill holder will always be a tiny bit off center by the amount of clearance in the holder. For most jobs, this is not an issue but when you need accuracy (like cutting key slots) then it does matter.
