UFS2 is actually a pretty fast filesystem for most cases. UFS2 does not currently support journaling, however some work is underway by Scott Long to implement this. UFS2 has soft-updates, which keeps meta-data consistant in case of system failure (reboots,etc), but does not avoid an fsck. The 5.x series and above has support for background fsck, which allows you to mount the filesystem and begin using it, while background fsck does the checking live. There are read-only ports of reiserfs and xfs available for 6.0- and 7.0. The reiserfs code is in the src tree, and the xfs code can be found here: http://people.freebsd.org/~rodrigc/xfs/ I'm sure Craig and Alexander would enjoy the help with the porting of XFS. I'm unsure of the status of reiserfs. Porting XFS to FreeBSD (full support) would be awesome!
