Thoughts on bokeh - 85mm (1.8 + 1.2) vs. 100 mm macro

[VonClev]

I was shooting the seasonal butterflys on flower bit with my 100 mm macro, and at the same time my 4 yr old son was hamming it up, so I turned the lens on him with a 1/125 exposure at f3.5 using my 10D. Great clarity, but also great bokeh. Thus my question, although the 85 mm f1.8 and 1.2 have been discussed here and elsewhere, has anybody contrasted these lenses with the 100mm macro? I've seen others use the 100 mm macro for portraiture, but am curious to see how the 100mm stacks up against the 85 mm offerings. Are either of these worth putting on the wish list if I already have the 100mm macro?

Thanks,

Chuck
