After using C1 since 2004 (admittedly, on and off at times, depending upon needs and desires), I will say ba-bye to C1 after version 23. I update sometimes every edition, sometimes every other, but with them going the Adobe subscription route, they can say goodbye to me. They are, frankly, stupid.
Virtually everything C1 does, I have one or two other software packages that do the same and many times better. (On a recent shoot, I had to abandon C1 because it couldn't keep up with my shooting. I often had to stop to wait for previews to generate. At one point I was up to almost 400 previews to be generated and it took 4-5 minutes to catch up so I could start shooting again.) I tend to use C1 tethered more for product shoots where it's not stressed by speed. I generally dislike the skin tones I get compared to LR. One of the best features is its sharpening compared to LR. For tethering, I actually prefer Smart Shooter.
So, after a long relationship, it appears to be time for a divorce.
