I heard they are good. I don't see how the XL would matter
I have an XL. when I bought mine it was only $180 on amazon, which is just a $10 difference rather than $30. even if it was thirty tho, I'd have gotten the XL. especially now that I have one. I've never used a regular 3DS but the size on the XL feels nice in your hands, and there's certainly nothing wrong with a bigger screen. pluuus longer battery life
I recommend the 2DS over the 3DS. The 3D effect is kinda buggy and very headache educeing. Anyways the 2DS is 100 dollars cheaper and still plays the games at the same quality.
but it's ugly and really awkward. if you can't quite afford a 3DS I would suggest the 2DS. but if you have the money to spare, I wouldn't get it. the 3D would be a lot nicer if you didn't have to be still while using it, but personally I've never had problems with headaches from it
