Actually, I was talking about the games themselves in terms of graphics, sound and actual gameplay. They are the freaking exact same thing.
If the aesthetics matter that much, then most of what you prefer about the 5200 is mirrored in the XL series. Quality construction, pleasant design, aluminum trim, etc. I won't defend the inherent cheap feel of the XEs.
But again, the games themselves are EXACTLY the same. And most of them (on the 5200) require a 3rd-party controller to be playable!
It's like having an Audi S4 with a worn-out, sloppy suspension. :-)
