If you like xfce, I think that kde is more similar to it than gnome. So I would recommend giving kde a try too.
An easy way to test out both is to just use a live image booted from a USB. You could always install them to your everyday PC but then you have a lot more packages installed and I personally would rather keep my installed packages to a minimum. If you can’t do a live cd because your os doesn’t provide one then I would try a vm or a different drive that you can boot into.
