: It'll be easier to debug if something goes wrong. If you daisy chain, one bad connection/wire, the whole thing doesn't work. It's like the Christmas lights where you have to check each bulb to find the bad one. The one drawback with *not* daisy chaining is a lot of wires.

Christmas trees lights are wired in series, daisy chaining grounds results in a parallel connection. I if a wire breaks all the buttons *after* the break will stop working, all the buttons before the break will work fine. So to find the break you find the last key that works, and then the break is after that key... not difficult at all.
