You can only stream console games with xcloud. That on top of better quality streaming and support for inputs besides a single controller can make GFN a valuable choice for game streaming over just xcloud. It sucks that you would be paying for two game streaming services thou.
It's nice if you already have GFN, but I wouldn't say it's a killer feature, as you can already stream Game Pass games with xCloud at no additional cost anyways, right?
