Have not tried M4 but E4 is the best “performance” mango I’ve ever had.
It’s TRULY deserving of the name “pina colada” because it tastes like a very sweet pina colada when soft. It’s more Sweet pineapple tasting when barely soft and very coconut and pineapple when a bit softer to touch. Delicious, phenomenal, spectacular mango with a real coco flavor, not that artificial coco flavor
Like “coconut cream “ has.
