There are a lot of gimmicks out there - but the pros don't use them. They use tools that, when mastered, let you knock out hundreds of terminations quickly and without failures. Often, after they've come through to wire a space, someone else entirely (or one man from the team) comes back and does the certifications - anything that doesn't pass has to be diagnosed, and that single diagnosis/correction takes more time to deal with than a whole drop does to initially terminate so you need it kept to an absolute minimum. So, these gimmicks appeal to the grievances of someone who's either afraid to take on terminating wires, or who has tried a couple times with improper tools/training and wants an easier way.
If you are willing to learn to do it the right way and with the right tools, you'll understand why it's the only way an experienced person would do it.
Of course after all that, I'll admit that my own home was wired with RJ45 ends originally in a structured wiring enclosure (not by me; done during construction) - I did relocate them to a wall-mount enclosure and wanted them in a traditional patch panel, so I did use the pass-through keystone jacks - but only because I was being lazy, and when I sell the house I plan to feed them back into the enclosure - so this means never re-terminating the wires - but I'd certainly never set out to do this from the start - I'd terminate directly to keystones on both ends - for residential, it'd be leviton guaranteed.
