Hi Robert, I have been using Sprint chemistry for over ten years now, and -obviously - am very satisfied with it. But I also use Neopan 1600 most of the time, and Yashica cameras with Zeiss lenses. You don't hear much about Neopan and Yashica either.(posted 8680 days ago)I think a large part of it is advertising. These products don't get advertised much [in this country for Neopan & Yashica], and it follows that they are not as popular.
I think one of the most important lessons I have learned in photography is to use what works for me - period. Every once in a while I go to a different film, camera, or developer, but most of the time I am happier with the way I have been doing things.
