I'm not sure. I don't like doing subjective comparisons, so I'll have to use AVISYNTH and do some SSIM testing.

More on the "--multipass" thing: It turns out that setting --vbrhq mode automatically sets the encoder to do 2 pass-full. So I'm not sure that there is actually any additional capability associated with that parameter other than it may provide a bit of granularity (with the ability to set 2pass-quarter).
