It's just a matter of taste mainly -- the modern 35mm print stocks are all good, they have strong blacks, which means that they are contrasty - yes, to some degree they are designed for making prints from intermediate dupe stock, which is what a film-out is usually made to, but they work fine for printing color negative. It's really that with the D.I. process, you can optimize the image off of the negative better for printing in terms of playing with the gamma, controlling the white and blacks carefully, and even applying some selective sharpening... but prints using a photochemical process work fine, as the Nolan/Pfister movies prove. I think they tend to look richer in terms of blacks than prints off of a digital negative, but that also may mean that they won't show all the dynamic range on the negative. But in the old days of photochemical post, you photographed a movie with the contrast of the print stock in mind, which is how Pfister shoots for Nolan.
But in the case of "Tree of Life" the other advantage of doing a 4K D.I. was being able to project it in 4K digital, which I suspect looked better than the film-outs.
3-perf is not a projection format -- 1.85 is achieved by projecting a 4-perf print with a 1.85 mask in the projector gate. The advantage of shooting 4-perf Academy, non-Super, is that you can make contact prints for projection with a soundtrack on the print.
