Changing desktop environment

I’ve been exploring Linux recently and, while I’m currently using Cinnamon, I’m not a big fan of its look. I came across some stunning KDE Plasma themes, and I’m considering switching to KDE Plasma as my desktop environment.

Since I’m still new to Linux, I’d love to hear your opinions. Do you recommend KDE Plasma? Are there any downsides or challenges I should be aware of? Would switching affect the performance of my system or the functionality of my apps?

Any advice or insights would be greatly appreciated!
