Here's a print I made from a negative I shot in 2008. Technically it isn't great, and I did overexpose the negative almost a stop. It's probably too small to really tell anything. The results do, to my eye, look a lot like Neopan 400 in terms of how it prints, tonality, etc. This is in Edwal 12 developer.
I like the film, and in most cases you can use an EI of about 80 for full shadow with most developers I've tried.
I would expect both Plus-X and FP4+ to have a longer straight portion of the tone curve. All three films have a gradual toe as well, not seriously abrupt like TMax. I wouldn't care whether I shot Neo SS, FP4, or Plus-X, really. All three films have been fantastic.
