Which is the best just dance? (Switch)?

I want to buy Just Dance for the Nintendo Switch but I don't know which one. There's a choice of 2018, 2019 and 2020.

What do you think, which is the best? Incidentally, I've never played Just Dance before, so I'm a complete beginner.

So I have all parts on the wii and I think the three of 2019 are the best

And why, if I may ask?
