Press fittings have a well earned reputation of leaking after a few years (they mostly rely on rubber o-rings that will dry out over a decade). They are rarely used by anyone who knows what they are doing.

Note that crimp fitters (which your link discourages!) do not have the same problem and are what most are moving too. Soldering still has a place, but is rarely used because modern PEX is so much cheaper and easier to work with.
