I was debating this for a long time as well. We ended up going with the 85L, and it was a great choice. The autofocus sucks and it's absolutely massive (heavier than a 24-70L despite being a lot smaller. I guess dense is a better description...), but it is so useful it rarely comes off of the camera. We took last minute wedding photos in a couple's front yard, but you couldn't tell because NOTHING behind them is in focus at f1.2.
That said, although I'm very fond of photos taken with the 135L, I've never used it. No one here rents it either, which is bizarre. Honestly I find 135 mm to be an awkward focal length for weddings. It's rather tight and limits itself to fewer situations that way. An 85 mm lens on a crop sensor is more or less equivalent to 135 mm on a full frame sensor.
