I sometimes use a steamdeck out and about but most of the time I use it at home streaming my desktop using sunshine/moonlight. I don’t notice the lag, just enjoy the high quality visuals and extended battery. You can even use wake on lan to wake up your PC from moonlight on the steam deck.
Actually I don't own a Deck, though if it's similar to Steam Link on PC I'd say moonlight let's me tweak a little bit more stuff like bandwidth and allows for up to 120fps on all my client devices.
The setup process for moonlight/sunshine is pretty easy so I'd say give it a shot.
