Not always and not for everyone. If you want to output a decent quality image to a TV to play on the couch, then the Steam Deck isn’t exactly a great choice because it can’t really do that, it struggles to maintain playable framerates in modern games at its own native resolution, nevermind a TV’s (either 1080p or increasingly often 4k). If all you play is older and/or indie games it might still work fine, but it’s not a one size fits all.
All I did was point out that no, the Steam Deck isn’t the best deal for everyone. Chill.
But since I’m back here already, if you’re trying to sell me the Steam Deck as a Playstation 5 Pro replacement I’d expect visual parity with at least the regular PS5, at comparable framerates. Which I know the Deck isn’t capable of. It isn’t a replacement for a stationary console or PC because that’s not what it’s designed to be. It’s primarily a handheld, designed to compete with other handhelds.
And I wasn’t going to go there but ease of use is also a major point in favour of the Playstation because you won’t have to deal with “getting around” things, ever.
Different people have different use cases which are best served by different devices.
