I use DU on virtually a daily basis...
Just as an example, I was given a couple of PM G5s today and was asked to format/zero the drives. I booted one in TDM and plugged it into my Macbook running El Capitan and couldn't figure out how to do it.
I then just plugged the FW cable into my Mac Pro running 10.9 and it took me about 30 seconds to get started zeroing.
I had 4 computers to zero, and wanted to do as many at the same time as I could. Literally every version of OS X I used(everything from 10.4 to 10.9) made it a breeze. I even pressed an OS 9 computer into service.
Although zeroing G5s is probably not an every day event, working with external volumes or troubleshooting another Mac via TDM is a several time a week event for me. It looks like I'm still going to be holding out with 10.9 for computers where I actually need to get work done.
