i didnt take any courses with either of them
but from some of what my friends said that
Abo ELhamayel he is less than the averege
Ghandisan is a good one not for explanation but for the exams and quizs like it all from the his notes
so it depends what u r looking for realy
i took ME 203 four years ago
i hope i could help u with the note but from what i heared that they changed the book … so i guess may note will note be that efficient to u
sorry but if u need anything more
i will be more than happy to help
take care
