I find that the 100 and 400 have pretty similar characteristics, which could be described as fairly high contrast, medium/high grain (for their respective speeds), and overall traditional looking.

I absolutely love the 200, which seems more like a TMAX style film and holds highlights very well. The grain structure is actually quite good for scanning and is fabulous under the enlarger. Highly recommend the 200.

Had a minor QC issue with 100, but I think the emulsion is just kinda soft.
