I have both charging docks. .
The original is simpler, you drop the 3DS in without a second thought and can use it while charging if you're desperate.
The new requires a bit of a fiddle to dock, gotta make sure you're putting it in right every time. The 3DS is unusable while docked. Stability is fine. But the footprint is tiny so it fits on my bedside table or desk so much better, and for that I prefer the new dock.
