I've sailed both. Nothing beats the N20 for beefy crews. Drives like a cadillac, even in moderate seas

F16 is great too, but a little small for big crew of 2. Good singlehander. F16 can fidget downwind, but new designs help keep the bow up

Ask anyone who's sailed an N20 how they compare to other boats for distance sailing or buoys. Too bad their sailplan is a bit dated which limits their peak performance

Yes, I'm a bit biased. In reality most of the current boat designs are pretty dang sweet. I think the only fleet I haven't sailed is A-cat.
