The short answer

MOTS-c vs SS-31: which to choose

On price they're close — about $16 vs $17 for the cheapest COA-verified listing. MOTS-c is the more widely stocked of the two (55 vendors vs 37). They target different goals — MOTS-c is a metabolic peptide compound while SS-31 is a mitochondrial peptide one — so they're often complementary rather than direct substitutes.
