No-one seems to have contributed here - a pity, since many of us commented on individual puzzles a lot!
Well, I write down a couple of ranking numbers for each puzzle I manage to do. One for difficuly, one for enjoyment. I suppose the "enjoyment" is pretty subjective, based on clues, construction, pdms, originality, surprise..... Each number is out of ten.
I have six puzzles equal top on 9 for enjoyment for 2016: Elap's Hailstorm, "The Bard"'s Bacon, Xanthippe's Philosophy, Shark's 4th Dimension, Poat's Hare (sorry - I got it wrong, but I loved both it and the controversy!) and Bandmaster's Advent.
Numbers? You want numbers? OK: 4386, 4406, 4409, 4414, 4422, 4427.
Choose one of these? 4406. By "The Bard".
