Which should you buy?

The lines differ in intent though: NAS vs Enterprise NAS — Western Digital Red Plus is tuned for sustained NAS writes and RAID rebuilds, and the same logic applies on the other side.}

Both lines overlap on 53 Synology models — if yours is one of them, either drive is officially supported.
