KDE 3 to KDE 4 transition really was painful, it pushed me away as well, but it also happened over 15 years ago. I gave it a shot a few years back, and it was great, much better than modern-day Gnome in my opinion.
Thanks for stating this. It puzzles me how people can still hold a grudge against the transition to KDE4 that happened back in early 2008. It took a while but even KDE4 got pretty good. KDE6 is great and if you follow Nate Graham's blog, you can see the improvements that go into it every week. https://blogs.kde.org/authors/nategraham/
I don't want to invest migration of workflows and time to understand a new UI paradigm for a system that once catastrophically crashed and burned something good on the altar of 'new and innovative and unfinished'.
That's not a grudge. It's growing older and setting other priorities in life.
