ProcessBuilder vs Runtime.exec()

Which one is better? By better I mean which one has better security, etc. (not ease of use).

Ease of use is the only real difference between those two.

Note that ease of use can lead to security by helping to avoid mis-use.

At least on OpenJDK 6 Runtime.exec() is implemented using ProcessBuilder:

public Process exec(String[] cmdarray, String[] envp, File dir)
    throws IOException {
    return new ProcessBuilder(cmdarray)
        .environment(envp)
        .directory(dir)
        .start();
}
