Getting away from the vs. threads for a bit...

I have a Twin Famicom and would like to be able to sit on my couch play for a change. I know there are a few variations of controllers that will work via the controller port on the side of the console. Which one is more worth importing? The Hudson Joy? Or the Hori? Or is there one I am unaware of? Controller cord length is very important along with the quality of design. Thanks!
