To get a 3DS, 3DS XL, or 2DS. What is a PlayStation fan to do.

You have five options: 3DS, 3DSXL 2DS, New 3DS, New 3DS XL. New 3DS isn't available in the US.

2DS has the cheapest price new, cannot be closed and has no 3D. The downsides are big enough I don't own one, so that's all I can say about that.

The main difference between 3DS and 3DSXL (also between the two new models) is screen size. As the resolution stays the same pixels get bigger on the XL. Some people claim that this is ugly and prefer the regular 3DS for that reason, but sales suggest the majority prefers the bigger screens. You can decide which camp you're on.

New 3DS has some advanced features. The big things in my opinion are C-Stick (the extra-buttons don't get much use) and stable 3D.
Games I tried that work better with the C-Stick:
* Zelda Majora's Mask 3D (looking around with the second stick instead of switching between movving and looking is so much more convenient)
* Codename STEAM: Looking around again, otherwise you would do that with the touch-screen.
* Monster Hunter: Again, without that you would use the touch-screen for looking, with the stick you can put other function to the touch-screen.
Games that work better with the stable 3D: Ironfall Invasion, Kid Icarus Uprising, Zelda Moajoras Mask 3D. Here is fast movement the key. The New 3DS (for me at least) helps to better keep the 3D. Other games with great 3D like Fire Emblem still work great with the old 3DS.

The new 3DS (not the XL) has changeable plates at top and bottom and you can get styled ones to make it look different. Practically you can get your special edition this way.
