Pfsense on nvme ssd: ZFS vs UFS

I was googling around to get some info on these file systems on pfsense and it seems zfs is really good for those without a UPS since its a write on copy file system as opposed to ufs and zfs is more reliable in that sense. However a lot of those posts were from last year or older and it was stated then that zfs isn't ready for production since there may be issues cause its new in pfsense.
That leads me to my question. Has zfs on pfsense matured to where it is ready for production?
I plan on installing it on an nvme ssd and i also plan on enabling ram disk since i should have a decent amount of ram free to do so. But for the unexpected power loss at my home (not usually often but only heavy storms maybe once a year) would zfs be stable? And is 8gb the recommended amount of ram for zfs or can i use 4gb?
Edit: also if i did have a ups for example, would ufs still be preferred? Or would zfs be the way to go?

You need more than 4GB RAM in order to enjoy zfs's file caching. I have three pfSense boxes running with zfs and M.2 stripes. No problems so far. I think the greatest advantage of zfs is that you don't have to think about how you want to partition the drive.
In case of heavy storms, one cannot exclude the risks due to induction damages caused by lightning...
