The bottom line to me for the 25mm FL and MFT is that -- all else being equal -- I want as skinny a depth of field as I can get. It's not that big of an issue at longer focal lengths, because you naturally tend to get narrower DOF, but separation can be hard to achieve at 25mm.

Robin suggests that the difference between f/1.4 and f/1.8 isn't significant here, but that's not my experience. Here's a comparison between the two apertures on my Voigtlander 25mm/.95 (roll over image to see the difference):

Given that the lenses both have excellent IQ, and the PL/1.4 can be had for close to the same price, I'd go for the PL over the Olympus. It's purely academic for me as I'm happy with the Voigt and I'm not likely to purchase either lens.

So there is a noticeable difference between f/1.4 and f/1.8 on your Voigtlander. The difference between the Panny 25mm f/1.4 and the Oly 25mm f/1.8 isn't nearly as noticeable, at least in Robin Wong's samples. What does that tell us?

I don't think it's clear at all that the DoF difference isn't noticeable between the two lenses.  Rather, I don't think Robin is playing it quite straight.  Notice in the shots with the peppers, for example, that the Oly shot is focused closer than the PL shot, which makes a big difference re: the background blur?  I think he picked his shots to downplay the difference.
