what everyone else said.
I think if I had to choose one of the ones you mentioned, it would be the reverse order from your list. Stihl first, then cold steel, then collins, in fact, I wouldn't accept a new collins probably - you could pay me to take it to the recycle center maybe. I believe Stihl axes are made by ox head or whatever the german version of that name is now, and should not be terrible - though it does look like the handle weighs more than the head which would be very bad, maybe if you could slim the handle to half the diameter it might be handy. I looked up that cold steel axe and it mostly looks like an axe, so it might not be bad.
as others have recommended, look into Council tools axes, there is one hardware store in my area that carries them - but that's mostly because the owner is a really cool guy that's into axes himself.
