Both Puyo Puyo and Tetris are amongst the most known games in the piece-falling puzzle genre (I suggest calling it Piezzles or Pazzling). While Tetris is obviously the most popular one, which one is better? I don't think there's a need to explain either, but just in case, you can see the objective in both games here:

All things considered, I'm siding with Puyo Puyo on this one. My skill is far from decent, but there's just something so satisfying about carefully placing each pieceonly to fuck it up and lose the round to make a huge combo that'll definitely give you an advantage. Also, Tetris doesn't have anything like Dr. Robotnik's Mean Bean Machine.
