Only if you are hung up on gnome of course. Plenty of alternatives that work out of the box in desktop space and flatapps aren't really needed really as one click with much less issues is possible many gui package managers.

First option for anyone coming from other OS should be kde. Defaults are sane and customizations are easy to do. Frankly I really don't know why all distros provide gnome by default. There are neither helping themselves nor the broader linux desktop community by shipping something that's broken in so many ways.
