On protein quality specifically, Whey Protein Isolate (WPI) scores higher — highest DIAAS of any common protein source — compared to Hemp Protein Powder, which is lit_estimate, lower protein density than other powders, modest lysine.
Cost is roughly comparable between the two ($$$), so budget isn't the deciding factor here.
If you're eating plant-based, this comparison is moot — Hemp Protein Powder fits, Whey Protein Isolate (WPI) doesn't.
Whey Protein Isolate (WPI)'s typical serving also delivers more leucine (2700mg vs Hemp Protein Powder's 1150mg) — relevant if the goal is maximizing the muscle-protein-synthesis trigger per meal, not just total grams.
The real deciding factor is dietary fit, not macros: choose Hemp Protein Powder if you need it to be plant-based, choose Whey Protein Isolate (WPI) otherwise — the protein numbers are close enough that diet compatibility should lead.
