There's a meaningful protein-density gap here: Beef Liver runs 26.3g per 100g against Tempeh's 19.0g, roughly 7.3g more per equal weight.
Beef Liver also carries the stronger amino acid profile (lit_estimate, complete animal protein), while Tempeh is DIAAS-adjusted, complete plant protein.
Budget-wise, Beef Liver runs meaningfully cheaper per typical serving ($) than Tempeh ($$).
The dietary-restriction question settles this for a lot of people before the macros even matter: Tempeh is vegan, Beef Liver isn't.
Beef Liver's typical serving also delivers more leucine (2050mg vs Tempeh's 1450mg) — 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 Tempeh if you need it to be plant-based, choose Beef Liver otherwise — the protein numbers are close enough that diet compatibility should lead.
