I'm not sure I would agree with the 'limited number of bands' - HF is a very wide territory, changing quite literally with the sun, so there's lots to hear, depending on what your interests are. At 16 foot, that antenna wouldn't be very efficient say, down on 49 meters or even lower. As Saint has implied with his description, there's a great many factors to consider when choosing an antenna. One of the most important is whether you can put up something outdoors and how much room you have.
Certainly the Par is one of the best - but 'the best' is very much in the mind of the beholder....
