fast or atomic efi ?

I,m presently installing the Fast EZ kit on my 500" stroker Super Bee this weekend.I went with a port injection kit put together by Scott Brown @ Competition Components, I wanted to run a dry intake vs wet. My buddy has the same kit and is happy with the cold starts and drive-ability.
