This should be fairly obvious...

ZFS has it's own requirements... to work well it needs lots of resources (cpu/ram) and EEC memory.

If you have those, then sure, it gives you many advantages.

If you don't, then you are opening yourself up for struggle.

ZFS doesn't need any more "resources" than any other kernel space filesystem. Deduplication on the other hand, does need a good amount of RAM, if you want to prevent the deduplication table (DDT) from spilling to slow spinning rust. However, if you have a fast, and large SSD L2ARC, the DDT spilling over to the L2ARC might not have drastic consequences.

Regardless, unless using the DDT feature of ZFS, it doesn't need anymore resources than ext4 or XFS.
