DC-37 was used for the external floppy drive on original IBM PC.
DD-50 was used for SCSI port on old Sun 3 and Sun 4 computers (I guess
some of these count as personal computers).

Ditto for D-21 Amiga floppy drive connectors.

Even the connector manuafacturer web sites are calling them DB9 and DB15
so I guess common usage won this particular battle.
