Obviously it depends on what games you want to play.
The one point I will mention in the Switch's favor is that I feel like it's a much better handheld. It's a lot lighter and I like the feel of the JoyCons better (or I did until mine went bad, we'll see how durable S2 JoyCons are). Still, both are ultimately too bulky for me to take on the go, instead I bought a Miyoo Mini Plus on sale and that's become my portable while the Deck gathers dust and the Switch no longer leaves the dock.
