If you've never done either crack or coke, Your FAR better off getting some coke, (granted I haven't ever done crack, but i know those who have), it is a longer lasting and more "fun" high than crack, the come-down is easy to deal with by smoking a bowl or two, (yeah you may feel a bit shitty the next morning but I imagine its nothing compared to the morning after smoking rock). And at least for me, i've never really craved coke that much after doing it. I'd say its both more enjoyable (for a longer time), and there's far less chance that you will lose your self control.
