– which voucher is more powerful for a single person travelling? the BA or the barclays?

Do some dummy booking based on where you would like to go and which class you’d elect to travel in. Amex is pay Avios for one-way for a return. Barclaycard is pay Avios for lower class for travel in a higher class. In my experience the Amex is more powerful in most scenarios, but YMMV.
Amex voucher also opens up more availability than the Barclaycard so in pretty much all ways I find it superior.

– will barclay allow me to upgrade the card?

In the Barclaycard app click:
More > Cards > Change to a different card

If you have the option for the Avios Plus card there you can upgrade, if you don’t you can’t.
