    I don't see it as a matter of better or worse, just different and redundant.

    Derrick was right on, "It does not matter what instrument is used to
    determine your position. You should be prepared with multiple instruments
    and methods."

    Jared stated, "The failure is unrelated to GPS, per se. 'A poor workman
    blames the tools.'"

    As Jared points out, the job requires tools-plural. Another tool analogy
    is, "When all you have is a hammer, the whole world looks like a nail." To
    too many new boaters the world revolves around their GPS. Other tools
    including DR are lost to them. GPS gives a fix that hopefully confirms my
    DR and other fixes, not vice versa.
