Currently both tools gives different view of io. While filebench simulates real workload, it cannot show what vdbench shows. E.g. we were doing some hardware array tests and it turned out (using vdbench) that the array works in a really strange way: sometimes its IOPS jumps very high, sometimes it lows very much. There were a few other tests where vdbench shows how IOPS behaves in each second of workload. I am affraid filebench _currently_ cannot give us the same data.
