Agentless is means replicate VMDK level and I see no difference between yours two options (please refer to my highlight below).
If my guessing is not wrong, you're asking for In-Guest (replicate in guest level) license on option 1, isn't it?
If yes then option 1 will be better RPO/RTO rather than option 2 but of course license price would more higher.
Please bare in mind that agentless license will be discontinue support by vendor next year.
Therefore, I recommend you propose In-Guest license to customer instead.
