My understanding is that plumbers use the expansion method of termination
because it is easier, faster & cheaper. They also donâ??t need to stock the
crimp rings.
I plumbed my shop w/apartment (4 sinks, 1 shower, 1 tub, 1 washer, 2 toilets &
2 hose bibs)using PEX & crimp rings. It was cheap & easy. That was a year ago &
I have no leaks.
In my house I used some shark bite connectors on a copper pipe & it started
leaking.
My use is just a single point but it worked fine for me. YMMV

I used PEX on my kitchen remodel in 2011. Maybe I didn't know any better but I
used the crimp rings on hot and cold sides, run to the icemaker, feed to
dishwasher. Everything is still intact. Only downside is that PEX under the
sink isn't as pretty as copper.
