IMO, the Dayton's look better, are cheaper, and will sound just as good. Not a bad choice if you don't want to make your own cables, they will be visible in your room, and you want something that is finished off better than plain bare wire.
If you're in the diy mood, you can always just order bulk wire from PE or monoprice or your local hardware store (whichever is cheaper when accounting for tax and shipping for the amount you need), connectors and/or wire cover/techflex type pretty stuff from PE and similar.
As for connector types, I like bare wire but it can be a pain at the AVR end. Spades IMO make a more secure connection, but I think it is partially dependent on AVR configuration and specific connectors as to what is secure and convenient, and largely a matter of personal preference.
