I am now using Acros, 35mm, with Pyrocat-HD (glycol) and like the results. I decided to standardize on a single developer a while back when Perceptol left the local shelves (only to return with a truly ridiculous price attached to it) and the Xtol price started to make me whimper when paying.
I liked Acros in Xtol (usually diluted 1+3). It gave full box speed, nice sharpness, and tonality. Same for Perceptol (again, 1+3, tried it for the cost advantage and the smaller package convenience). The dilute Perceptol/Acros for dusk/night photography was beautiful. Good sharpness, speed, shadow separation, highlight control, and reciprocity characteristics.
I'm sorry I don't have any scanned samples I can show you - no suitable scanner. I don't shoot people so I can't comment on that, but for weathered woods and stone (and old buildings and equipment) I like it a lot.
