SWIM's Q on the difference between Crank vs. Crystal

[tweekerdope]

I know this is all hypothetical, but humor SWIM because some questions seem to buzz around in his mind and he never remembers to get them answered.

So anyways, SWIM is curious, if you had a cook make two batches and suppose they were the exact same quality and purity. If the cook goes on to take the next step to recrystallize one of them then he is left with a pile of crank and a pile of crystal. If they are both meth would they both be the same purity, one just prettier, and in the end get you the same amount high?

I'm just wondering if there is any plus to crystal, besides that it took a while before people figured out nasty shiz to cut it it cause crank is easier to cut since its just powder? This is just my own theory from watching SWIM get high all the time, but he has no knowledge outside of how to light a pipe and suck in smoke, so I wanted to clear up this debate.
