I think the higher the focal length has better compression, but I am mostly street / portrait photographer which sometimes you need that distance to the subject.I will test both and see..

I don't like to use that term, "compression," but some math nerd can probably figure out how much blur happens with the two lenses wide open. The 135 has the longer focal length, and also the longer distance effect, versus the faster aperture of the 85mm.

Use the tool at

http://howmuchblur.dekoning.nl/#compare-1x-135mm-f1.8-and-1x-85mm-f1.2-on-a-0.9m-wide-subject

Note the assumptions about subject distance, etc. For the case I tried the 85f1.2 was the blur winner. For closer than a head shot the 135 mm can be the winner

If you want headshots that are totally in focus with the greater bokeh the 135mm clearly is the winner. This is because you would be shooting at least f2.5 irrespective of the lens and compression often become a deciding factor. But there are other variables such as distance to subject/background that can either strengthen or weaken the effect of bokeh at any focal length.
