Verdict
The clearest difference is ads: NutritionFactor at none against Emotion Diary's shown. NutritionFactor also leads on update cadence (every 2 weeks vs every 5 weeks). Emotion Diary's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.4). On price and in-app purchases there is nothing between them.
