I certainly think the batch solution is more appropriate. The batch
interfaces will be more consistent across different gpg versions,
while the numbers/letters you enter at the prompt can quickly change
if different algorithms are supported in a new version etc.

So stick with the batch and with-colons interfaces whenever you can.
They are also easier to script -- computer-readable and all that.
