Against UFS, of course [1] :-) Their hype is "our journal is faster than UFS", which is probably true. They have extent-based allocation, which is good for their greatest hype - performance with databases (see all the marketing shredder-food about [Cached] QuickIO). They have hot resizing, which fast as hell (again, compared to UFS), they have snapshots, which are cool. And don't forget the GFS capability, which I am yet to see in action. [2]
So in Solaris world, for large filesystems, Veritas is the winner. I am really looking forward to seeing how will they do in the OpenSource world.
[1] Actually they benchmark Oracle on raw devices vs. Cached QuickIO, too. [2] Even tough the options are expensive, in my experience all of them work perfectly.
