I guess you haven't had Joy-Con drift :)
The Joy-Con drift is embarrassing
But at least the Switch OS has no oopsies (that I've seen.) :)
My [New] 3DS has also been rock solid for years, hardware and software.
But I never minded much, because they kept replacing my 3DS because of the scratches, and back then, your 1-year warranty would reset every time a repair was done. So I just kept sending it in, and kept getting a brand new 3DS every year...
Some would consider the lack of folders an oopsie but that's probably not what you're referring to.
3DS is indeed a damn solid device, though. Nintendo did really well with it.
