[G4] HFS+ vs. UFS for Panther boot partition on G4

[Aaron]

I have a few hard disks that I'll shortly be reformatting. While I'll probably format one of them, at least, to boot into OS X on earlier Macs, I want to format one to be best for running OS X on my G4 Dual MDD. I'm wondering about the advantages of the UNIX file system vs. HFS+ for the OS X boot partition.

I realize that files on such a partition won't be readable when booting into OS 9 and I'm thinking that this may be an advantage, since I could put data files there that I don't want to be easily read by somebody who doesn't have my password. I'm also guessing that OS X will run better on top of the UNIX FS, since it is, after all, UNIX-based. Also, I may be running raw UNIX occasionally.

Aside from not being able to move the disk to a machine that can't handle UFS, what other disadvantages might there be to using it? What other advantages?
