Not the strongest because Steam Machines with Alienware had problems and way too early during development of Proton that games couldn’t handle well. The controller was stolen IP and is still currently fighting the lawsuit. VR games are not great as people expected and rarely do new VR games arrived. Leaving the VR headset in storage for mostly the owners life. Lastly, the Steam Deck original has problems and announced updates or free ifix fixes just to not have drifting problems. Still the Steam Deck after the original has some issues with compatibility and deleting their data every update.
The company has poor track records for hardware. Valve is like the Sony of gaming, they lie about stuff and make you sign up to download the game in their closed ecosystem.
