A few weeks ago I fired up a Punch Punch from June '18. By far the absolute worst cigar I've had this year. Tighter than my dear old aunt (financially speaking - before a certain admiral jumps in) and when I opened it up a bit with a draw poker it burned hotter than - oh, I probably can't say that.

At any rate it really really really sucked and I finally tossed it. Almost an hour of pure aggravation. I did break it into pieces which made me feel marginally better about the experience and ended things on a high note.
Last night I smoked the one that had been laying next to the devil cigar in the box. It was everything it's brother hadn't been. Perfect draw, subtle flavors transitioning from woody to dark roast coffee, great smoke production, an excellent overall smoking experience. One of the best I've had in recent memory (which is admittedly spotty). Ya just never know.
As far as the absolute best this year so far, I'd say probably a '15 Double Edmundo.
