PS4 or Switch

I don’t own PS5, but I have PS4 and switch. Wondering which platform is the better option to get? How big of a difference in graphics and experience is it between the two platform?

I work full time with a side business I’m working on at home outside of business hours. A husband and a parent to teenagers.

With this busy lifestyle, I’m leaning towards Switch so I can play at night time or other slot of available times without having to set up anything. Can also play during kids watching tv or playing instruments.

Thoughts?
