I'll just second what the others said. Its prefernce, but if you're going to use it for nonMK games then you don't want the MK layout.
That said, i love playing on the MK layout stick I got. Its fun, and its easier for me to do moves than with the pad. I don't fat finger the buttons anymore, although my accuracy with the stick itself could still use improvement. But that will come. I don't reget it at all, and its made me a better player.
