There are other advantages, for one expansion fittings are closer to
full flow.  It also requires good quality tubing (pex-a), and not the
cheap stuff on offer at the borg. It's also possible to tell visually
inspect the joint and see that the fitting is properly installed.  The
joints also tend to get stronger over time,as the pex wants to
contract to its original diameter, so it grabs tighter on the fitting.
Expansion fittings do require an expansion ring, so they do have extra
parts to stock.
