~Sweeping is a better option because all your bitcoins from your paper wallet will be sent to one of the wallet addresses and so you will still be able to recover it later.
i really can't see a scenario where sweeping is a better option though.
- if you want to spend BCH, like by sending it to an exchange, sweeping is just adding an additional unnecessary step and you may have to wait a couple of hours for 1 confirmation on your first tx to spend it again if the BCH blocks are being found with delays.
- if you want to hold BCH then just hold on to that paper wallet, it has been safe so far and it will act the same in the future.
- and finally in case you have used that paper wallet on bitcoin chain and wanted to move the BCH from it to a new paper wallet again sweeping will add an additional step. just create a new paper wallet, import and send the funds to that new paper wallet.
