I, too, suggest getting the sample packs & trying them for yourself... it's a very personal thing!
On that note, I love, love, love Unjury Vanilla (& I do use the unflavored in a pinch, but it's nowhere near as good). My fav "recipe" is the following, I love cinnamon-spicy things... I have it at least once every day:
1/2 carton of vanilla micellar milk (20 g pro)
1 scoop vanilla unjury powder (20 g pro)
1/2 scoop Big Train low-carb spiced chai (got it from
Bariatric Eating - Protein, Vitamins, Gastric Bypass & Lap Band Info, Post-op Recipes, and Help)
3-4 ice cubes
blend & enjoy!!
Good luck finding your protein!
