I prefer the 60mm. Much cheaper, stabilized, macro capable.
the 60mm is also very nice for portrait photos (a bit less dof than 85mm, but sharper image).
You have the DoF reversed at least according to conventional terminology, where at wider apertures the DoF is narrower. Also, for portraiture 60mm is on the wide end of acceptable, more suitable for group portraits. For shooting torsos and head shots, longer focal lengths are better because the camera won't be close enough to the subject to produce perspective distortion, resulting in noses being larger, ears smaller, etc.
These two lenses were designed differently, where the 60mm is optimized for using smaller apertures and the 85mm is optimized for using wide apertures. According to Photozone's tests, both lenses are very sharp in the center and very close at all apertures until the 85mm tanks at f/11. In the sides and corners of the frame it's a different story, and the 85mm is more uniform across the apertures and outresolving the 60mm until it catches up somewhere between f/5.6 and f/8. This is unusual for macro lenses, which usually maintain high resolution across the frame at all apertures.
It can be tricky reading PZ's resolution charts, because the numbers are valid only for the resolution of the camera's sensor. In this case both lenses were used with the NX200, and the numbers indicate that the 60mm macro lens doesn't fully utilize the resolution that the NX200 offers, at least when its wider apertures are used. The 85mm's results are inconclusive, and we won't know whether it will perform even better with a higher resolution sensor or not. What we do know is that Nikon's 85mm f/1.8 and f/1.4 G lenses (with the right bodies) far outresolve both of Samsung's lenses on the NX200. In fact, used on the 24mp D3x, the extreme corner resolution at all apertures is better than the highest resolution that the 60mm and 85mm could attain in the center of the frame at even their best apertures. Samsung's lenses appear to perform better than the Nikkors when they were tested with Nikon's D7000, but that's because the NX200's sensor has the advantage due to its higher resolution 20mp sensor.
My conclusion is that the 60mm Samsung macro lens is pretty good, but was a better match for the NX100. Samsung's 85mm lens has the potential to do even better if Samsung ever produces a higher resolution body than the NX200/NX20 but for now, the 85mm is the lens of choice for anyone that needs to shoot in low light, because it has a substantial resolution edge over the 60mm at all of the wider apertures, from f/1.4 up to nearly f/5.6, and of course the 60mm macro lens goes no wider than f/2.8, where its border and corner performance is really pretty poor.
I also prefer the 60mm as an overall lens, thanks to its focal lenght.
Can't argue with personal preferences. For a single focal length lens, both are pretty long to use as a walkabout lens, where most photographers would choose something between 30mm and 40mm (for APS-C sensors). So here I'd agree, that the 85mm would be much too long, where it would be better suited for use in a studio. Here are links to some of PZ's lens tests that I commented on, for the pages that include the resolution charts and tables.
