For what it's worth, a highly scientific measurement from my house in 
Berkeley, the authoritative location for all quantitative evaluation of 
the Internet, using secret proprietary round-trip latency-measurement 
tools...

    a.nic.de, 100 packets, 7% packet loss
    round-trip min/avg/max = 163.454/199.368/494.708 ms

    c.de.net, 100 packets, 2% packet loss
    round-trip min/avg/max = 15.071/46.131/724.957 ms

    z.nic.de, 100 packets, 3% packet loss
    round-trip min/avg/max = 180.9/222.723/578.468 ms

    s.de.net, 100 packets, 0% packet loss
    round-trip min/avg/max = 184.26/219.786/501.547 ms

    l.de.net, 100 packets, 1% packet loss
    round-trip min/avg/max = 170.435/211.573/568.7 ms

    f.nic.de, 100 packets, 5% packet loss
    round-trip min/avg/max = 171.717/206.826/489.947 ms

Overall for DENIC: 3% loss and 15ms / 166ms / 725ms min/avg/max latency.
c.de.net is the one I'd be using, and it gives 2% loss and 46ms latency.

c.de.net is the one you WISH your resolver would use.  sometimes
it might, others it might not.
