I found GO BIO tickets to have the best value per basic points right now on short haul, even without the 5000 bonus points. They are a few percent cheaper per mile than PLUS BIO tickets. (of course a PLUS ticket has catering, if you care, and it also earns more miles net in total, so if it saves you an extra flight to requalify, it might be beneficial).

I did not check how things look on long haul.
