Good topic, and one that I have given some thought to since the thread started.
Ruined? No, I wouldn't say that. Speaking for myself personally, I am not a "collector" of knives. I purchase knives based on their ultimate utility and what function/purpose they might serve long term. I haven't found anything that can top CRK, but there are some that are certainly in their league. The Spartan Harsey Folder is an incredible knife, I spent a year with one - if you are so inclined you can read about my experience here:
https://www.bladeforums.com/threads/one-year-with-the-spartan-harsey-folder.1902410/ . I own quite a few Medford knives, polarizing as the maker might be; definitely a quality contender. I have a slew of autos - mostly Pro-Tech - they are wonderful, I really can't find fault with them.
I rarely carry those anymore however. I don't really see the point in doing so; I am not one that really seeks out having something new in my pocket everyday. I guess it's similar to my choice in firearms; I don't change up my carry. Moreso with a firearm, familiarity, reliability and training play more of a role than anything.
CRK are my measuring stick, no matter what competes for my attention, I always compare it to a Large 21 or an Inkosi. Boring maybe, but they are my barometer.
Let's face it, CRK's can be considered boring - a titanium folder (inlays not withstanding), no flipper or "spydie" hole to fidget with, no bearings, no mokuti/zircuti, timascus, etc ... but for me they are just pragmatic and utterly reliable.
One day maybe, I would like to at least handle an Arius or a Grimsmo Norseman; but I am not doing anything to actively seek one out.
