Those vouchers come with so many restrictions (no residual, dont cover fuel surcharge) - its a borderline scam.
Always take cash.
Indeed.
€600 in cash straight into your bank account, which you can spend anywhere and anyhow you like, is worth far more than a €900 voucher that can only be spent with an airline that the OP says they won't travel again, and which furthermore is subject to any and all further arbitrary restrictions that the airline imposes on its use (such as TAP's restriction of the voucher to have only 1 year's validity).
The airline would much rather that you spend that money with them - or, indeed, let the voucher go unused. Why would you go with the airline's preferred option, unless you are a frequent TAP traveller?
