Is the 3D effect better on the orginal 3DS or the XL?

[ToraTiger]

So I'm trying to determine whether I should get a normal 3DS or an XL since I don't have a lot of money.  Is the 3D effect better on the original and is the XL pixelated?   I mean it should since it's the same resolution and stuff and you can't really fix that.  I searched google for this but the results were pretty inconclusive. 

So what are your opinions for people who have tried the regular and the XL.
