So I finally got them both...
Texture: is thicker and has a more genuine milkshake-like texture. isn't bad and is thicker than most, but Myofusion just has the texture nailed.
Taste: Trutein is sweeter, but they are both absolutely amazing. So great that it makes me feel good to re-read the labels to remind myself I'm not cheating. I have a sweet tooth, so the tastes are quite similar when I add stevia to the Myo.
Macros: Trutein has the Myo beat in most ways. Less carbs, no use of brown (like the Myo does), and BCAAs.
The verdict, I'll be buying more Trutein based on superior ingredients. But either way, it's nice to be into fitness during a time when you can actually consume products that taste like a legitimate dessert and still be properly feeding the lab (I refer to my body as "the lab" since we like to do experiments in it...).
