I favor running a journalling FS. You're much less likely to get corruption from a crash. If you do crash, your system will come up faster. The performance hit is negligable.
I've used ReiserFS in the past on my laptop. I favor ext3 nowadays. It's supported by most rescue CDs and can be used as an ext2 FS. The ext2 tools (fsck, resize, etc) are very well developed and tested. I've been using ext3 on LVM partitions on top of 2 IDE drives in a RAID-1 setup. Resizing works very well with ext3 for me.
If speed is of utmost importance, check out the others. I think ext3 lags the others a bit.
I think XFS has better support for ACLs and large files. Does SAMBA use the ACLs to better emulate a windows file server's permissions, etc?
