The stiffness is the first major difference. The 20K is pro level stiffness and the 16K is a decidedly mid-level skate. The tendon guard is cheap and flimsy on the 16K and the quarter would be much less durable. It all depends on how often you are skating and how big you are. If you're only skating once a week in a rec league, then go with the 16K. If you are playing competitively 3-4 times a week, you really should go with the 18K or 20K.
