Type of PEX?

I have decided to replumb my home (townhouse) using PEX. From an earlier post I will replumb using the standard single line layout vs a manifold.
I have a couple of questions I would like answered before proceeding.

1. I looked in Lowes for examples of PEX and parts for the pipe. Is ZURN Pex a good brand for replumbing?

2. Should I use the copper or stainless crimp rings. Zurn cam out with stainless crimp rings and a ratcheting wrench for them.



Thanks

Use SS crimp rings, we use them all the time.
