I've used Neopan/Acros 100 and 400 in 120, both developed in D76 1:1. Never tried it pushed to 1600. It's an interesting film - not a bad one, but not my taste. I prefer HP5+, TMax, or TXP/TX(35).
IMO it has a steely(?) look? Different, a little on the "dreary"(?) side? Hard to articulate the subtle differences between black and white films. It definately has a distinctive signature - noir-y(?) and it depends if you like the look or not. I prefer the Kodak and the Ilford stuff in the few my few trials, particularly HP5+. The Fuji is "overdramatic". Not sure if that makes sense.
For high speed stuff, I like TX(P) in diafine @ 1000 best of all, and I've gotten good results with Ilford 3200/120, so I stick with those.
Try it. See if you like it. Fuji seems committed to B&W, and I admire that. There may come a day when it's Acros or nothing, and if that was the case, I'd happily shoot Acros, and "learn" to like it more. Right now, though, it's not the one I plan to re-purchase, and have no desire to give it another go. There's too many others I prefer or others I would like to try.
