It's a very personal preference.
Do you like to have 2-3 games and focus on beating them? Low space card and delete them when completed
Do you like to have all kinds of games for all kinds of situations? One big card or a few cards always with you
In multiplatform games, do you prefer to play them on the go with your switch? One big card or a few cards always with you
Do you have a couple of games and one arcade type for quick play sessions? Big card
In my case i have the switch only for switch exclusives i like. 128gb is enough for me so far.
For anything multiplatform i play it on my GPD win 2. Pc master race
