@tubetime It depends on the overall requirements of the board. Questions I might pose are:
- Is the device sensitive to noise?
- Is it likely to radiate EMI?
- What enclosure is used? Is it metal? Is it continuous or are there holes?
- What other connectors exist?
- Is the USB port power-only? Is it data only? Can the device be supplied from multiple sources?

You always need to take the entire picture into account, there is no flat out right or wrong.
