Re: what are the differences?

This is not an exact answer but this article series may help you understand depth of field,subject distance and focal length

This refers mainly to tele and zoom lenses however the Focal length of the macro may help you achieve what you are looking for. For example the Takumar F4 100 ml macro will even at f4 work well in isolating subjects or portraits. However Shorter macro lenses such as the DA35 have a shorter working distance and when used in a normal way may not isolate distant subjects as well as close subjects.

Where i found the article helpful is dispelling the myth that aperture is the only way to achieve subject isolation or a blurry background. Focal length and subject distance also has an effect.

So back to your question if isolation or Bokeh is what you want a Longer macro will work best. If you prefer a shorter focal length such as 35 then you will either need to get in close (Macro) or use a normal lens which will have a longer minimum focus distance combined with a faster aperture such as a fast 50 you can also isolate the background.

If you are looking for a garage sale special then you can also get a good deal on a fast Pentax M50 f 1.4 or f 1.7 and get a reversing ring for some macro capabilities

...Either way my answer may not be totally complete but hopefully it helps some
