It isn't, the point is that it's not as "feature rich" as Lightroom. But, Lightroom has been out there a long time and has time to mature. I still see C1 as one of the new kids on the block. If you're paying for your Adobe subscription (and need it to get PS) why pay for another product that's inferior to the one you get with Adobe?
It's all personal opinion, but you can customise just about anything in LR.
But this was what you quoted from my post:
"and C1 is designed around the concept of being able to customise almost every aspect of the workflow"
and this is what you said about it
"And the Adobe solution isn't?
That statement alone shows how "blinkered" people can be on one piece of software."
So it is the point because you are clearly writing about my statement on customisation, which was part of me just trying to help a new C1 user.
As I explained it’s the customisation capabilities of C1 that are one of the main reasons I prefer it over LR. Once set up I find the workflow in C1 faster and more logical than LR, and the equivalent tools in C1 tend to work better and easier in C1 than LR, except the database, which C1 should be ashamed of, but I don't use it, and many people seem to find it works fine.
As a raw processor there is no way C1 is inferior to LR, different, but not inferior, and for my purposes a better choice and worth the money. But I'm not judging C1 on features I don't see as important for a Raw Processor to have.
There are very good reasons to stick with a LR/PS workflow, but for me the benefits of C1 offset the benefits of having a LR/PS workflow. I wish they didn't as I could well do without the additional costs involved. Which is why I review this every year when it comes to upgrade time. including studying the customisation capabilities in LR, and so far I have always paid for the C1 upgrade.
I'm not sure where you get the new kid on the block idea from. C1 has been around for longer than Lightroom, indeed Raw Shooter which was set up by a break away group of Capture One engineers, was bought out by Adobe, to bring their expertise into the Lightroom development team.
It was because I was a Raw Shooter user that I got a beta of Lightroom 1, and a free full license to the first release, and I have been a LR user ever since.
Although C1 is now my main raw processor (though I am increasingly using Raw Therapee) I still use Lightroom several days a week as a DAM, and on average at least once a week for image processing, but this is often in bursts when doing a LR or LR/PS course or tutorial.
Overall, both are good programs, with both having their share of good and bad points.
