    F.o.i.l or Box??????????

    What is the better method the F.O.I.L method or the (I am not sure of the offical name) box method(where you make a box with 4 squares) to factor. Are there any other methods availible?

    Whichever one you can do faster. I use foil, because I usually do that in my head.
