If you're curious, you can try out GeForce Now free of charge with any of its supported titles, they just limit your sessions to 1 hour and deprioritise you in the queue when there's high demand. I've found it generally works very well, but with the occasional hiccup. I can't comment on how it compares against the other services, I presume they're roughly as good as each other.
