While most of us are willing to answer questions, it would be helpful if you did some initial research yourself.

I'm not an expert on the subject, but, here are some articles I found via Google.

Also, the FreeBSD specific Wiki:

Note: Better is subjective, personally, ZFS will never replace my UFS/FFS partitions.
