Ys II kept the charming nature of the first game and fixed nearly everything that I didn't like about it. Better bosses, better environments, the combat feels snappier, and the addition of magic gives the player more options. It's just all-around a better game to play. And the music continues to be amazing! I still don't enjoy the massive labyrinth type areas near the end, but the game was enjoyable enough for that not to be a massive issue.
