To me all of the, not Kodak or Fuji, is a bit of a "if you can't make it, fake it". There's an under supply situation with conventional high quality color negative films. Alternatives are being offered, that will fill the needs of some photographers, that's great.
Similar to using alcohol as a substitute for gasoline in a car. It works in many cases. Not sure if it makes good sense, but IT happens.
I look forward to seeing if Adox (and others) can figure out a way to make a product that I find suitable. (I would be surprised)
Even in the days of several huge companies producing color negative film I was loyal to Eastman Kodak. I grew up with Ektacolor S, VPS, etc and now and have been loyal to Portra 160, and occasionally Portra 400. Last few years have come to enjoy Ektar.
If I had to choose just one color negative film, it would be Portra 160.
