How hard is Fedora for a Debian user?

Hi. I'm recently considering doing my first distrohopping from Debian to Fedora, as I'm going to get a laptop with NVidia GPU and "Debian + NVidia + Wayland" experience has been horrible in my environments. Since I want to keep using KDE as my main DE, I think I will give Fedora a go.

So my question is: how hard is this distro for a Debian user? Of course I tried it on VM for like 30 minutes, but I'd like to hear about it before installing onto real machines. I think the difference between apt and dnf is notable, but is there any other big differences?

Thanks in advance!! :3
