My experience with push fit and press fit is that if they aren't perfectly done (or have a manufacturing defect) they can appear to be secure, only to fail catastrophically at some random point hours/years in the future...
With a solder joint or a traditional compression fitting (the ones with olives) it's obvious if the connection is no good.
