I'll also add that it's a woefully underpowered system for the generation it was in and that is where my dislike of it comes from mostly (I did have one)
I loathe Nintendo's business practices and internal culture and miserliness and legal-threat bullshit. But damn if they didn't nail the Switch's design and portability.
I spent hundreds of hours playing monster hunter 3U in bed on the gamepad and never had a problem with it. I found it pretty comfy and the steam deck basically copied its ergonomics so they must have been doing something right
but regardless the pro controller exists which can be used in like 95% of Wii U games and has an abominably long battery life
