The difference won't be in subject sharpness. It will be in out of focus areas and transitions.
I'm always critical of people who comment on a lens and post images, without a comparison image. Your lens did great. A lot of lenses do great. I am a little dubious of the out of focus areas, I suspect they could be better. But trying to do a comparison when you don't know how far away the background is etc. is pointless. The possibility is still open that you might look at comparison images and go for the DFA 85. We won't know for sure until you do an actual comparison, even for you. You can't evaluate what you don't have in your hands.
Even then, I own the DA* 55 1.4 and have no plans to by the DFA* 50 1.4. It's better, but that doesn't mean I'll buy it. There are a lot of considerations in going with an older lens that wok against buying a new lens. You seem to be saying it's because of the properties of the lens. But it's also, you already own a good lens. It costs you nothing to keep shooting with it. It'll cost you $2500 CDN to get a DFA*85. That's a lot of incentive for you stick with what you have, regardless of lens quailites, so your decision is likely not relevant to anyone else.
We've had many of these kinds of discussions over the years. What they often come down to is the person claiming their lens was better than the 31 or whatever, really didn't know what to look for.
