All of the below applies to the Arista.EDU Ultra/Fomapan films, not the Arista.EDU/Forte films.
There have been reports of QC problems, but I've had few or no problems with the 35mm rolls I've shot. (A couple of frames do have some odd artifacts, but I'm not 100% convinced they're film QC issues.) It's very hard to judge reliability/QC issues based on anecdotal reports in Internet forums -- the samples are too small and unscientific.
I can say that, in 35mm at least, the film has little or nothing in the way of an anti-halation layer. Street lights at night, chrome reflecting light in bright daylight, etc., tend to produce halos. IMHO, this is the worst feature of these films. I don't know if the same holds true in MF and larger formats, though.
What I do like about these films (especially in 100 and 400) is the grain pattern. It's unusually crisp, even in developers (such as D-76 and XTOL) that normally produce mushy grain. These films are coarser-grained than T-grain films, but in my subjective judgment aren't grainier than other conventional films of similar speed (Tri-X, Agfa APX, etc.). Others say they are grainier than these films, though, so take my comment with a grain of salt. The APX 200 doesn't produce grain that's quite as crisp as the 100 and 400 do. Of course, this is likely to be much less important for LF users than for 35mm users.
I've seen the claim that these films resemble Agfa's APX line more than any other, but I've shot little enough APX that it's hard for me to comment on this.
