There are plenty of compelling reasons to choose either a Steam Deck or Nintendo Switch, though some key factors may push you further towards one or the other. Firstly, your choice of games and existing library matters a lot. If you own a sizable Steam game library, then the fact that the Steam Deck will likely support a great deal of them will be a huge incentive to choose it. Although the Steam Deck is more expensive than the Nintendo Switch, playing games that you already own is always cheaper than building a new library. That said, exclusive titles like Super Mario Odyssey are a great reason to pick up the Nintendo Switch. If raw power is your main concern, the Steam Deck is the clear winner. Still, the Nintendo Switch wins out when it comes to battery life and portability. Before you come to your final decision, make sure that you weigh up which of these factors is most important for you.
