Well .... this is an impromptu impression so excuse me if this comes across somewhat disorganized. I am going to type what comes to me as I am typing.
The zap filter Z's have a bigger, more powerful sound. The zap units are also more upfront, brighter and more dynamic, especially at the frequency extremes. There is more bass weight with the zap filter. The Ori is more refined and polite sounding. The Ori has more depth to the soundstage with a more relaxed perspective. The Ori has a beautiful midrange and does very well with acoustic guitar and vocals. Decays to notes seem to hang around slightly longer with the Ori. The Ori has very good bass that emphasizes definition and texture vs weight and power.
The zap units also have an excellent midrange but dont seem to emphasize the mids as much. There seems to be more going on in the bass and treble with the zap filter units. The Ori is great when you want to relax while the zap units energize you and have infectious PRaT with rock and blues. The Ori can do rock but I have to tube the amps differently with somewhat edgier and faster to tubes to get a comparable effect.
Most importantly, as far as satisfaction I am very, very pleased with either. If I had to pick only one I am very smitten with a Zhalou 2.0C / zap filter unit I bought used from Azure. This unit was originally modded by looser101 for swt61. This unit should never have been sold. But, I am glad it was for whatever reason.
