Ubuntu 21.10 more stable in comparasion of Kubuntu?

I tried Kubuntu 21.10 with backports enabled a few days ago, and most of the stuff I tried (Crossover, Display fixes, application installs) didn’t worked out that great, I know I may have got into this trouble myself with the backports stuff, but I still feel that KDE is more glitchy than some users would like to admit.

So, I was wondering if Ubuntu 21.10 was a little bit more stable for those who have been using it for the past weeks.
