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.
