I don't understand what you and others are saying about this claw issue. Do you find yourself able to use the right stick and press buttons on the Wii U, PS4, or XB1? I never have.
I can, and have since around 2001.
On the previous gen controllers (or at least, anything that's like the dual-shock design; PS1->PS4, Xbone/360, & Gamecube) I have these marvelous little things called "shoulder buttons" that I can use my index and middle fingers to press while using the analog pads. That's up to four simultaneous inputs that my thumbs will NEVER have to worry about.
Now, there are obviously other buttons on the face of those controllers for your thumbs to press, but smart game design (at least, where 3D camera controls are involved) will place important/timely functions on the shoulder buttons rather than the face buttons; or at least, those functions you're most likely to use while using the analog sticks.
The problem arises when you're missing one of those sticks and have to use other controls to make up for it.
On the 3DS, this means either sacrificing the ABXY buttons to use as a surrogate D-pad , OR using the touchscreen and stylus. The latter is exceptionally awkward, because it doesn't just alter how you input commands, but how you hold the entire unit. (and the awkwardness applies to left or right-handed folks, but lefties have it especially rough since the circle pad is on the left side of the 3DS)
Since you have to dedicate at least a finger and thumb to holding the stylus, this negates both the advantage of the shoulder button, and comfortable usage of ABXY buttons (which become EXCEPTIONALLY awkward to press).
Kid Icarus: Uprising showcases this design failure completely. It's possible to learn how to "claw" the buttons you need, but your hands pay for it.
Without some automation of the camera system (which isn't possible in all 3D games), those control concessions limits game design options, which is why handhelds need to stick to 2D games or slower, turn based games (Pokemon works great on handhelds for this reason).
I encourage you to at least try something like Kid Icarus Uprising, or any PSP-original port of Monster Hunter and then compare it to a contemporary 3D-camera console game. If you still don't notice the difference, well, allow me to officially welcome you to Earth on behalf of humanity, lizard-folk. ;p
