How they compare: the verdict

Modern Aminos takes this matchup by a razor-thin margin, 7.88 to 7.79 on the published formula. Its biggest edge is transparency, where it scores 5.5 against Loti Labs's 3.0.

It isn't a clean sweep. Loti Labs actually edges ahead on operating history (7.2 vs 4.9), so if that factor matters most to you it's worth weighing.

On lab evidence, the heaviest-weighted factor, both Loti Labs and Modern Aminos have independently verified third-party COAs, so the gap comes down to the other categories.

Across the 19 peptides both carry, Modern Aminos is cheaper per unit more often (Loti Labs wins on 2, Modern Aminos on 17). The price-for-price table below has the detail, per mg (or per IU or mL for products sold that way).
