What the numbers say
The best and worst flavors overlap. Quest's best, Quest Protein Bar – Double Chocolate Chunk (170 calories, 11.8), beats every Pure Protein bar. But Quest's weakest flavor, Quest Protein Bar – Chocolate Peanut Butter (10.5), ties several Pure Protein flavors. The flavor you pick matters about as much as the brand.
Pure Protein is denser; Quest is leaner per calorie. Pure Protein bars are listed at 50 g and Quest bars at 60 g, with about the same protein. That's 40.0 g of protein per 100 g for most Pure Protein flavors vs 33.3 g for most Quest flavors. Quest's edge comes from fewer calories per gram of protein, not a heavier bar.
Highest-calorie bar here: Pure Protein Protein Bar – Lemon Cake at 200 calories (10.0). We have a brand-site price for only one Quest flavor (Pumpkin Pie, $2.96) and none for Pure Protein, so there's no value verdict yet.
Which one should you pick?
- Calories are your budget: Quest Protein Bar (classic) (10.5–11.8 g protein per 100 calories).
- Most protein in one serving: Quest Protein Bar (classic) (21 g).
- Price: we've only confirmed a price for Quest Protein Bar (classic) ($2.96 a serving, $1.48 per 10 g of protein), so we can't call a value winner yet.
- Taste: check the shared 👍/👎 votes next to each product on The Hoard Board. They never change the rank, but they make a good tiebreaker.
Caveats
Pure Protein's AMMMAZE bar (Pure Protein AMMMAZE Protein Bar – Blackout Cake, 9.1) is a different product line and isn't included here. Serving sizes differ between products, so compare the protein and calories, not the package.
