i prefer crimp on bananas. reasons why: no oxidation, easy to connect/disconnect, more contact area than spades and easier to fit into tight amp jacks, etc. crimp because if you crimp that baby hard enough youll get the best bond you could ever expect. the disadvantage to bananas is that over repeated insertion they can lose some of their springyness which in turns makes them a looser fit. however you can fix that by getting a kind with a slit down the length of the banana so that you can spread them wider when the time comes (if the time comes). audioquest makes some bananas (called bfa crimp) like i speak of, nordost does (called z plug), and im sure someone else does or you can make some if you feel impelled to. id pick them of the material that your wire is made of, i.e. if your wire is silver then get silver plugs, gold/gold, etc.
