Nuance In B&W Photos

I shot photos of a model yesterday, and when I was looking through the shots from my SD14, they seemed underexposed to me. Luckily I shot some of those at ISO 50 and 100, so I was able to bring up the exposure a lot. The color looked weird to me though, and I decided to make B&W out of them. I was just playing with them in Aperture, so I was using the OOC jpegs. Here is what I got from the OOC jpeg in Aperture vs. what I was able to make in SPP with the raw file:

OOC jpeg converted to B&W in Aperture (many adjustments)

Settings for above image (only some are visible).

RAW converted to B&W in SPP 6.4.0

Settings for above image.

I probably could have done more with this if I had been using a Merrill camera or a Quattro camera, because I think SPP gives more control over things that can be adjusted with the files from those cameras. I wish those controls were available for my raw files from the SD14. Still, I think this turned out o.k. compared to the OOC jpeg, which follows:

OOC jpeg as extracted, using SPP 6.4.0

So the nuance is what I wanted to post about. The differences between this image above, edited with Aperture, vs. the B&W that I made from the raw file in SPP is in my estimate just small, but significant. The highlights are not blown in the SPP version, and the eyes do not have the really dark areas around the edges of the irises. The hair and bright spot next to her left eye on her face is not blown either, but since I could not adjust the black point, I had to use the contrast slider, and I don't like the affect of that as much as when using the black point slider. So I imported the jpeg created as a B&W from SPP into Aperture and adjusted the black point and contrast and some other things and got this:

RAW to B&W conversion in SPP (with adjustments) to Aperture as jpeg and edited in Aperture.

Settings for above image.

So ultimately, what do you prefer? In a way I like the more contrasty image that has blown highlights, but nicer looking skin (because of my use of the red slider in the monochrome mixer - not visible in the screen capture of my Aperture adjustments), but I don't like the model's eyes so much in that image. I guess the best thing for me to do would be to use layers in GIMP to make a version with parts of both images. That would probably be the best way to make it the way I would like it best.

Which one of these look best to you and why?

Would you like to play with the image? Feel free. Here is the raw file:
