Verdictwhich should you buy?

S1R — High-Resolution Landscape, Commercial & Studio Photography: A 47MP full-frame resolution powerhouse with one of the finest EVFs ever made — the S1R rewards careful, deliberate photography.

A6400 — Content Creation & Vlogging: The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
