Whats the best keyboard for music production?

I am looking for keyboards to build my home studio. And yes Im getting usb mics (audio technica) pop filters, reflexion filters, and a presonus usb soundcard (I have a hp pavillion dv4 laptop). I am now looking at keyboards and I need suggestions. I am currently looking at the Behringer U-Control UMX610 61-Key USB keyboard, and the Casio LK-220 61-key Keyboard and it is also USB. I just want to know which one is better and if you any please give some other suggestions. Thank You in advance.
