ZFS encryption on a disk can perform better than LUKS since LUKS has integrity enabled by default and TRIM/discard can't be used. If you encrypt the full nvme this can lead to premature drive failures and loss in performance. With ZFS there are other things to consider as well, but I would recommend looking at an article like here https://arstechnica.com/gadgets/2021/06/a-quick-start-guide-to-openzfs-native-encryption/ https://arstechnica.com/gadgets/2021/06/a-quick-start-guide-... that goes into much detail. Like always it mostly depends on your use case/scenarios.
