BIML, you either love it or hate it - either you use it to totally generate hundreds of packages or a bucket load of data flow components all at the push of a button or you are perfectly happy using the SSIS editor, you can see how the package is made up and drag the little lines from one task to another and it is simple right, why bother using xml that is more complicated, you only need to create a single package with a few tasks on it, maybe a script component here or there.
