I have four Perlick 425's on my kegerator. Perlick stopped making them about 5 years ago, but they have the removable spout and still are still working great for me. I too have a bottle/growler filler screw-in adapter for the 425's exactly like the VM one in your article.
Thanks for sharing the article - if the 425's were to fail I would definitely go with the VM's.
I run just a teensy tiny smudge of keg lube between thumb and finger run around the threads where the spout goes on to make removing and putting on the spout easier, and less likely to lead to cross threading.
