I waited to purchase a 3DS until the release of this inevitable second iteration. I have not had the opportunity to see the original 3D effect was. But this is it anyway sharp, with a viewing angle (3D effect) of approximately 90 degrees with "super-stable 3d" turned on. See no reason to have super stable 3d rejection when the viewing angle is minimal = torticollis. I discovered that it has a bit more difficult to correct the 3D effect if it is very dark (read: carbon black).
I chose the smaller version, so it would fit in your pocket. The console feels solid built and sits nicely in your hands, buttons, click the right (not squeaky or too soft feedback). Slider joystick and c-stick leaves a good deal to be desired, but it can be a habit as well, right now I have a little difficulty with finprecision at them. The choice to go with a matte plastic surface of this machine is a plus in my opinion, less greasy fingerprints.
The biggest minus is the price, considering that the power adapter is not included (there are cheap knockoffs, so you do not throw out two hundred pieces to just for this), the low screen resolution and above all the high price of the games. The screen resolution still feels quite ok according to me, however, that the 3D effect and the games should work fine (screen is bright with good contrast), but it has become accustomed to smartphone resolution and can not go back, I can see that it is a little difficult for this. However jacket 3D effect most of it (as long as you do not hate 3d;)).
The hardware has been upgraded in this version, I was wondering first if this would cause it to be warm when playing, which it does not.
It has many stars, but you can hold out so it can probably be worth it to wait for a sale.
