Crop camera or FF? There is a 1.6 difference, so any answer would take that into account.
Do you have a zoom lens to see which focal length you like. Both lenses are excellent, the 85 is bothered with loca's at wide apertures with shiny objects. It can be removed in lightroom.
Even with FF, a 135L has a lot of reach, I usually use mine 30 or more feet away.
