And yet, while the games are obviously based on the same mechanics, I find 2048 to be the better game because it is simpler. 2048 gets right to the point, and is trivial to understand. This is an important design point that is often missed: games often work best when they can be easily discovered. Stuff that slows that down (unnecessary complexity, a UI that slows down how fast you can iterate on mistakes, etc) can impact how "annoying" the game is perceived to be.

(I do they're both good games, though, and could see how either could be preferred)
