Punchdown Keystone modules vs Coupler Keystone modules?

I need to consolidate several 24-port 1U patch panels in high-density 48-port patch panels (our server rack is too small)

I saw this 1U 48-port voice patch panel going cheap:

However, then I saw fs.com also has new empty 48-port patch panel:

Then you can get their coupler keystone modules - you just plug in RJ45 cables in each end:

What are the pros/cons of this, versus your normal keystone module that you punch down?
