I shopped comparative and the first point is obviously the smaller or larger screen on this point I compared the number of IPR. 120 DPI for the N3DS and 96 for XL, so a lower resolution for the XL and a sharper image and less aliasing (jagged) for n3ds. I would take the XL when it has a decent resolution. But if for you the size and comfort are significant do not hesitate to jump on the XL. I think a portable console must be PORTABLE so slight, small and portable, then the question arises not for me.
I was surprised by the size of the box, really small, or it is that I do not usually. Same for this new3DS I found smaller than what I thought. It is "cute" hotel. But with my big hands I do not know if it will be handy when the keys will be severely tested. In the box there is the new3DS (seriously?) The boring books, the front shell to set very easily, and a small bag with augmented reality cards. Without charger, so buy it separately! The configuration at power not rocket science (internet, 3D, username, date of birth etc ...)
I tested Super smash bros and Zelda Ocarina of Time. In game graphics are really gorgeous, 3D brings a little joy even if it gives a better effect depending on the game with the ability to increase or decrease the 3D. Surround sound that gives the impression that the sounds come from all sides. Battery life varies between 5 and 6 am if you do that the game, which is not bad for those who play on the adventure of Pokemon or Zelda. But disable 3D if you cut the pear in two. Side customization you can customize your interface color or pattern (paid) and then customize your shell (only with n3ds not xl), I have ordered the mario shell, thank you amazon!
Conclusion: This is a very good console with a wide choice of interesting games, buy eyes closed. If you want a real console that is portable and with better image quality, the n3ds is for you. If you want a big screen, a better grip, but with a lower quality image, it will be the XL.
Speaking of grip, if you are rather the type to play intensively on being lengthen console: I recommend to those who have big hands like me mason, games like Super Smash Bros. or Super Mario 3D Land AC should be relatively simple, but once the Sylet becomes indispensable it goes bad. Edit: Finally no worries, simply get used to it!
PS: Do not rely on the poor quality of the display on the photo, it's just the camera that gives this effect.
