This isn't close. Pea Protein Isolate packs 80.0g of protein per 100g against Tofu (firm)'s 17.3g — a 62.7g gap driven mostly by how concentrated or diluted each food naturally is.

Tofu (firm) pulls ahead on protein quality specifically (DIAAS-adjusted, complete plant protein), even in categories where Pea Protein Isolate wins on raw grams.

Tofu (firm) is the more budget-friendly pick ($ vs $$ for Pea Protein Isolate), worth weighing if cost matters more than the other differences here.

Pea Protein Isolate's typical serving also delivers more leucine (2100mg vs Tofu (firm)'s 1300mg) — relevant if the goal is maximizing the muscle-protein-synthesis trigger per meal, not just total grams.
