Yes, http://oss.oracle.com/~mason/seekwatcher/ext3_vs_btrfs_vs_xfs.png 
is a recent visual indication that comes to mind.

I mostly prefer ext3 because it has never really failed me (only once 
when I forced a fsck on a mounted FS - got about 2% of files back). XFS 
is my filesystem of choice when large files and/or parallel streaming 
reads-writes are used. One gotcha is default yournal size (or metadata 
buffer size ir RAM) - default used to be smallish and this resulted in 
relatively slow metadata operations (like deleting a huge source tree). 
There's a mount option to increase the RAM buffer size, or maybe 
creatinga bugger journal during mkfs also helps.
