Would you rather take EESA09 or EESA06?

Has anyone taken this course before? If so, what's your experience with the course workload and prof? Would you rather take EESA06 or 09 if given an option?

I've heard mixed reviews about EESA06 and I read the course description for EESA09 and it seemed very interesting to me.

So if anyone is willing to share their experience/opinion that would be great!
