Argireline (Acetyl Hexapeptide) vs SNAP-8
Argireline (Acetyl Hexapeptide) is mainly studied for expression lines, skin appearance. while SNAP-8 is studied for expression lines, skin appearance. The difference is in the mechanism and the evidence, not in which is "better": it depends on the goal.

How they differ
Although sometimes mentioned together, Argireline (Acetyl Hexapeptide) and SNAP-8 do not target the same thing.
