Get the switch and move up to the Xbox in a couple years. Nintendo easily has the most child friendly game library, and the portability is good for kids as they won't be hogging the TV all the time + can take it to their mates gaff and play it in the car or whatever.

Xbox is great and game pass is fantastic, with a decent library of kid friendly games. but for a five year old... switch is without a doubt the way to go.

PlayStation's demographic is casual adult gamers. They have some great exclusives, but not much child friendly stuff deffinately not the right choice here

Also I saw you talking about Minecraft, I've not got a switch and someone says it doesnt run great, but you can always Bluetooth a controller to a tablet or phone and play that way (or with touch controls if you really want). In my experience Minecraft can run on anything bar a toaster so I'm surprised switch has issues. Regardless. There are plenty of ways to play Minecraft, and save files and realms (personal servers) should work fine across all devices as long as you are signed into your Xbox account 👍
