If you're running bulk wire, you'll need to terminate each end with something. Punching down is in my experience a bit harder to get right than
crimping a plug. But not so much harder it's worth crimping your own cables to use a passthrough jack.
IT Professionals usually hire an outside contractor to run the wires and do the punchdown, use their Fluke tester to provide a certification for each run and warranty they'll come out and fix it if it fails. If you're doing it yourself that's a bunch of different steps you're unlikely to do as well.
If you're running premade cables, then having a panel like this is definitely superior, and the cables are probably better made than what you can do yourself too. The only trouble is getting the right lengths.
