ZFS on Linux will provide you all the goodness that it brought to Solaris and BSD.

XFS seems like the most obvious and maybe safest choice. FWIW, we use it on SL5 and SL6. Ultimately any issues we've had with it turned out to be hardware-related.

ZFS has some really nice features, and we are using it for larger filesystems than we have XFS, but so far only on BSD rather than Linux...
