Optimum nutrition creamy vanilla is the smoothest one I've ever tried. No chalkiness at all. Earthchimp has an unflavored and unsweetened one you might like. Plus it comes in a compostable bag.

Optimum nutrition vegan vanilla has been my daily for years, 2 scoops in my banana/strawberry/yogurt smoothie, I never get sick of it. Also their whey chocolate. I used to be obsessed with Planta vegan powder “chocolate candy bar” flavor, but got sick of it eventually, and it’s pricey

Vegan Gym has a video where they test 72 vegan protein powders. The only vanilla in the top 5 (and my fave too) is Optimum Nutrition's Plant Protein Creamy Vanilla.

Looks like a large firm (Glanbia) bought up these three companies: Optimum Nutrition (ON), Isopure, and Think. * **Think** → Facing a class action lawsuit over false labeling. [Source](https://topclassactions.com/lawsuit-settlements/consumer-products/food/think-class-action-claims-protein-bars-falsely-advertised-as-containing-no-artificial-sweeteners/) * **ON** → They changed the formulation for their plant-based protein powder, and it tastes like shit now. Can personally confirm. [Discussion](https://www.reddit.com/r/veganfitness/comments/xbnfbv/new_optimum_nutrition_plant_protein_formulawtf/) * **Isopure** → Also changed its formulation (seems like for the worse). To top it off, Glanbia tried to give their CFO a €750,000 “retention” bonus.

Bulk nutrients was $19/kg once upon a time, now it’s around $30? It is what it is I guess.. they’re my go to still. ON Chocolate is the best tasting by far, but also more exxy by around $70
