I enjoy using GeForce now in the private beta for free, but from what I heard their pricing was going to look something like 25$ a month or something ridiculous like that.

Compared to that, Stadia is free at 1080p, and 10$ at 4k, that's much cheaper. They also have in my experience better latency, and support more devices (any pc/laptop with a browser, chromecast, phone, etc).

Good points. I think the value of each offering greatly depends on whether you already have a Steam (or similar) library of games.
