There is nothing in the rules that specifically defines what kind of wire connectors you use. Just make sure that you follow the wire gauge guidelines for the circuit, and use appropriately sized connections.

That said, using terminal blocks like you linked are going to take up quite a bit of space, and might not be as easy to use as you imagine. Many teams use Anderson Power Poles without issue (mine included). I'm curious what issues you had with them in the past, and if there is anything we can do to help make sure you're using them correctly.
