I really like DGS2 - it's got the unique privilege of being a direct Ace Attorney sequel, picking up its predecessors' plot beats and relying on the player to know where all the characters stand. This lets it tell a really energetic story by the series' standards, bringing both games' overarching plot to a close while still having time to slip in some great mysteries and incredible moments (case 3 is probably one of the best cases in the series.)
The one big gripe I have is that because it has so much plot to run through, and it relies on the player knowing and caring for its characters, it loses some of the character focus that made DGS1 so unique. Three years later I keep thinking about the massive reveal/twist at the end of the third case that basically nobody reacts to beyond the brief cutscene it takes place in. It should shake a good chunk of the cast to their core and instead they're kind of like "damn, that's crazy! Oh well."
