I just have a PS4 and I like it a lot. I don't have a switch but really want one, so badly! Hee hee.
I think the PS4 and Nintendo switch are just completely different systems and have very little similarities. The switch can't compare to the graphics of the PS4 and arguably can't compare to the hardware either. But the focus of Nintendo has never been on either of these things. Nintendo has always been a pioneer, exploring two things:
1. How can we engage non gamers and invite them to play?
And 2. (Answering their own question)
We do that by creating a new experiences around how people play games! What can that look like?
We saw this with the Wii's system, introducing motion controls, and we saw this again with Wii U system, offering a table control! And we are seeing it agin with the switch!
The switch is the first and only console that offers handheld and counsel gaming in one unit! Nintendo doesn't focus on graphics and speedy/flashy hardware because they are more concerned with the experience of the counsel itself. What can we offer that no ones else has been able to? What makes us different? Nintendo in my eyes, has always been the odd one out, of the three major counsel giants. Doing stuff that is just weird and different But that's what makes them so special and magical! They aren't afraid of what people think, they take chances and risks....
Anyway all that to say that, PS4 is a great system if your looking for beautiful graphic and impressive hardware
Nintendo switch is a great system if are looking for a counsel that will give you a different experience on how you play games!
Nintendo is such an odd duck but that's why I love them. Everyone else is arguing over themselves about who has the more powerful system, but then Nintendo is like "yes, but is the controller shaped like a remote that you can bowl with? Can we add more screens? Can you weigh yourself with it? Check your pulse? Is there a mini-game that involves milking a cow- I think that would be a real hit at parties."
Very hard to say, as I don't have a Nintendo Switch. Hopefully, if I win the latest iMore contest, I'll have one and will be able to provide a more informed answer to OP's question! I have a PS3, PS4, and we have a Wii at my parent's house that has not been connected for a few years now. The PS4 ROCKS! Games, gameplay, graphics, you name it, it rocks! I know my biggest peeve w/the Wii was the TERRIBLE graphics. I have not seen anything related to the Switch other than the logo and I think the console? controller? I hope Nintendo has stepped it up and games are now in HD; they still looked 8-bit on the Wii!
