But in terms of rendering style or "flavour", they're different - and I'm not specifically referring to shallow DOF work here, neither corner-to-corner sharpness. The two just have different rendering character, yielding a different effect/look to the images.
Thus a lot depends on what one is looking for, photographically, from the aesthetic point of view.
In fact, even among the Three Princesses which share much commonality, the 43 imparts its own signature character, a (subtly) distinct look from its two siblings, the 31 & 77.
Oh sure it is not exactly the same, FA43, on top of its bokeh/pixie dust has an FA color rendering. Less constrasty by default, maybe a bit warmer. DA35 has very constrasty color rendering, very deep blacks. For that it is similar to DA15 and DA20-40. In some condition it can provide its own pixie dust/rendering in its own way, quite diffferent from the FA43.
Now with PP by touching at micro constrast setting and in DxO what they call "DxO clear view" you can in the right condition increase quite a lot the 3D pop of a lense and with DxO Film pack, you can control the type of color rendering you want. I'am not saying you make the 2 lense give the same results, but theses tools give you much more control and possibilities in term of rendering than have just 2 different type of lenses for rendering. This is the equivalent on film to choose your film type or on lightroom of what some plugins do provide.
Now sure, I do recognize the interrest of having great lenses and use the lense specificities to help creativity. This is just that again that if I think I need both FA43 and DA35 ltd, this mean I could likely find 1-2 more lenses arround this focal range and I could do the same for many other focal range. I would end up with 20-30 lenses at least with a few quite expensive and objectivelly this would not improve my photographic practice that much. But it would control a good share of money, more than I'am willing to accept and it would also complicate my life as a photographer. I don't want to have to wonder for 1 hour what lenses I should put in the bag and to wonder why I didn't got this specific one in the end that would have better rendered this subject... That's not fun - to me - at all.
I really prefer to have a few lenses, each one carefully choosed, but this choice can be made one time, and not to made over and over each time I go out or take a photo. Each lense I own will be best for some kind of shoot and for each focal length range I try to find the one that best mach the most likely usage I would have with it. That's why I got FA77 instead of DA70 and why I got DA35 instead of FA43 or FA31.
