I’ve had both installed on my machine without issues. Jumped back and forth until I decided Gnome wasn’t for me.

I prefer KDE. It works well out of the box and offers a good amount of customization. I tried gnome for a bit and didn’t like it.

What I like about Linux is that it’s easy to switch between DE. Just try out a few ones until you find something you like. I can recommend looking into Cinnamon (the DE of Mint).
