1.      It's certainly a helluvalot easier to make a traceroute server
        lie, than to make LSRR lie.

2.      Typically one wants to test from MULTIPLE borders of a given
        network to ensure that they are doing shortest-exit properly.
        A traceroute server is useless for this, unless you have one
        attached to every router.

3.      There's a significantly higher probability that a traceroute
        server might be down, than that all backbone LSRR might be
        down.

4.      With LSRR, it works the same way for everybody. No need to
        keep a database of address<>traceroute server correspondances,
        no need to worry about the subtlties of parsing other people's
        traceroute output [which version of traceroute did they use?
        do they let you specify arguments, etc., etc.]

Clear?
