I have been tempted by GNOME several times, but I disagree with some of their design choices and find them a bit frustrating. I feel that it's fairly strongly-opinionated software. The benefits, of course, are obvious: internal consistency that leads to a higher quality experience. But, only if you buy-in to some overarching design philosophy. That's one of the reasons I left Windows! I also have a suite of Kwin scripts that make my life a lot easier, so it's pretty hard to leave Plasma at this point.
Still, that keyboard has tempted me a lot nonetheless...
