Everyone going to this would ruin games. These streaming services will always have compression artifacts or jitter which kills immersion. Worse they will be more expensive over time than hardware. Even worse your games can get deleted and you won’t own anything. Worse there will he ads put into the stream.
Price is comparison will be variable. If you're chasing the highest specs and framerates, you're spending more than streaming would cost. As for artifacts, I played most of Assassin's Creed Odyssey at the highest specs through Shadow and noticed barely any difference between the gaming rig I have, running it at the same settings. And I still owned the game, it was installed from my Steam library. Not owning is a legitimate concern with something like Stadia, but not most other services. Ads in Streams? Again, maybe for Stadia if they release a free version, but for most services where you're basically buying a friendly front end to something like EC2 and running from your own library of games, no- Ads are not an issue. You're already paying for the commodity computing, and Amazon or whoever will no more insert ads to game streams than they would an RFP session.
