It depends on the person. I've found that I use my Switch a lot on the go, like on public transit or when I'm staying at my family's houses. I wish I had gone with a large-size MicroSD card to store my games so I wouldn't have to change the cartridge each time I wanted to play a different game however, it is entirely up to your playstyle. In the near future, I will be buying myself an SD card for this reason.
