The 827 is built with thicker aluminum sections. Which one is better is a matter of what you want. The tornado is a great antenna, but is lightweight aluminum it's almost 1/3 the weight of the 827. The 827 uses thicker aluminum sections for sure. The 2016 is just about like the 827, the 2016 is about 1.5lbs less in weight. The 827 weighs over 13.22lbs so better have a good mast setup or tower for it if you plan on going up very high with it. As far as which is better, the 827 and tornado are both 5/8th wave antennas, the 827 most likely the better antenna due to the beefier aluminum, but both probably perform about the same at the same height. JMHO.
