sorryNeither model seems appropriate, considering your thread is currently in the Vintage Diving & Equipment Forum, where we celebrate and deploy underwater gear of the sort designed between the late 1940s and the mid-1970s. During that period, both Mares and Cressi made excellent all-rubber model fins that would be perfectly compatible with vintage diving. For example:
Mares GTX

Cressi Rondine
View attachment 699051
They come in a full range of adult and children's sizes and there are modern replicas in the case of the Cressi Rondines, e.g. Oceanways Aquapro full-foot fins. Open-heel Scubapro Jet Fins might also pass muster as efficient and historically accurate fins.
As for the Mares and Cressi fins in the images you have posted, they represent at best the sort of composite fins western diving equipment companies marketed from the 1990s onwards.
If you have posted your message here in error and want advice about modern fins, repost it in the Fins, Masks & Snorkels Forum, where you are more likely to receive the advice you are after. If you take this course of action, be sure to define what you mean by "better": whether better for you (hence subjective criteria will apply) or better for the diving activity you are contemplating (so objective criteria may apply).
No need for an apology. I hope you arrive soon at a solution to your dilemma.sorry
