Beef Liver is in a different weight class here, protein-wise: 26.3g per 100g vs Tofu (firm)'s 17.3g, a 9.0g difference that's more about food category than food quality.
Protein quality is essentially matched between the two — both land in a similar tier for amino acid completeness.

The dietary-restriction question settles this for a lot of people before the macros even matter: Tofu (firm) is vegan, Beef Liver isn't.
Beef Liver's typical serving also delivers more leucine (2050mg vs Tofu (firm)'s 1300mg) — 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 Tofu (firm) if you need it to be plant-based, choose Beef Liver otherwise — the protein numbers are close enough that diet compatibility should lead.
