The "true successor to the 3DS" is a smaller Switch

[A Black Falcon]

I'm sure I've said this plenty of times before, but I strongly disagree with the idea that capacitive touch is precise... that is, unless you're talking about capacitive touch with some magical super-accurate, not awful squishy-tipped stylus, which might exist out there but definitely isn't cheap or included with the Switch. If you're stuck using your finger, though, it's a bad experience, just like all finger-controller touch is. I can't understand why people like using fingers on a screen for anything beyond the most basic of phone experiences, it's horrible for gaming! Games on a touchscreen need precision, and you get that from the reactive touch screens of the DS, 3DS, and Wii U. You do not from the finger-based touchscreens you find on the Vita, Switch, tablets, and such.

And that's why Sushi Striker is a lot better on 3DS than Switch. It's also why Mario Maker 2 will probably be better with its button control option than the touchscreen, because fingers are far too large and imprecise to give you the kind of precision you'd need to match Mario Maker 1's controls! It's sad that almost all touch has abandoned precision and plastic styluses in favor of multitouch and fingers, but while that's a fine move for a phone (where convenience is important and you mostly don't need precision), but it's awful for a game console. Unfortunately most people seem to not be bothered by this, oh well... I still play puzzle and other touch-based games on the DS and 3DS all the time, but it only took me a couple of tries at them on my tablet, Vita, and Switch before realizing how bad they are with fingers. It's not close. I don't want to play touch games on the Vita or Switch, no thanks, not with finger-based controls.

There are even special styluses you can get for capacitive touch screens.

I've tried several. They stop working all the time and those awful squishy soft tips are only a moderate improvement over a finger in precision. Again better options may be out there, but they're not common. I've always been of the opinion that capacitive touch is bad for game consoles and have seen nothing to change my mind on that.
