[Watch Movement Value] Which movement out of Sellita/Miyota/Seiko would you say is the best value?

All things being equal and me loving the watch, which movement below offers the best value for money?

Sellita SW200-1 @ $449

Miyota 9015 @ $299

Seiko NH35 @ $199

The Miyota and Sellita has an open back and decorated custom rotor, bridge, and blue screws.

The NH35 has closed back with no decoration.

Am I missing something or is the Sellita the best value?
