best way to make connections

So after discovering my problem was a bad connection from the start it dawned on me that maybe im not choosing the best method. Im wiring in my MSD and ignition using Garnder Bender connectors, but splices, spades ect ect. Is there a better method? Id like to make it so I can unhook the box with ease without having to cut wires all the time. Suggestions and products please?
