At least here in Boston, everyone is using crimp rings. No one is using
the expansion rings anymore and they are getting increasingly difficult
to find. I sold my expander to a guy who'd been looking all over for one
as he had a stash of expansion rings.
I have used Sharkbite without issues, but the surface needs to be
exceptionally smooth; hard to do if you have a solder drip or can't get
in there with emery cloth to fully clean it up. .
