Both are serums built on the same key active: Vitamin C. That makes them genuine alternatives, so price, texture and the supporting ingredients decide it.

C-Firma Fresh Day Serum

A two-part serum activated at first use — 15% L-ascorbic acid + ferulic acid + vitamin E + pumpkin ferment. The fresh-mix model addresses vitamin C's instability, but the price is hard to justify against SkinCeuticals CE Ferulic for essentially the same chemistry.

The reference-standard antioxidant serum — 15% L-ascorbic acid, 1% vitamin E, 0.5% ferulic acid, formulated below pH 3.5 (the L-ascorbic acid standard from Pinnell's Duke University research). Demonstrably increases photoprotection when layered under SPF. Expensive, but what every other 'CEF dupe' is trying to be.
