I have looked at all the PEX connection types - I like the Wirsbo / Uponor system the best, and it seems to have the following of most all the pro plumbers. The Viega ProPress seems good too. My question is this - the other two major connection types, copper crimp or stainless steel clamp - which one is the better system? To me, the SSC seems like it should be better as it will not be as susceptible to thermal expansion/contraction failure as the copper crimp I think may be. Thoughts, opinions??
